How to succeed in maths.......

Step 1: Hard work trumps natural talent.

As in most everything, the people who are most successful in math are the ones who work the hardest--not those with "natural talent."   In school, those who work hard get better grades in math than the "smart'' students who just coast.  Most aspects of mathematics can only be learned by hard practice.  This holds true whether you want to develop your problem solving abilities or your computational skills.  No one thinks they can run a marathon by using only their natural talent, but there are lots of people with no talent for running who have worked hard and have successfully completed many marathons.

Step 2: Keep an open mind.

In math almost everything you learn is useful, even if you can't see it right away.  All the formulas, theorems, ideas, proofs, and problems you study in high school and college are connected to lots of real world applications, even if you don't see them now.    And more importantly, even if you think you'll never use the specific things you are studying, they help develop your mind and make it easier for you to solve other problems later--the problems you really care about.   It's like boxing: training programs for boxers often involve lots of jumping rope.  A boxer might complain "When am I ever going to use this? I am never going to jump rope in a match."   But jumping rope makes them better boxers, even though the boxers never actually jump rope while fighting.   The math you are learning is much more useful than jumping rope; but even if you never use it in your daily life yet, it makes you smarter.  That is the most important reason to study it.

Step 3: Find the reasons--don't just memorize.

Mathematics is not just a long list of random formulas that someone invented out of nowhere.  Math works because it is true--there is a reason for every step, every rule, and every part of every formula.  Don't just memorize the formulas and the rules.  Find out where they came from, why they work, and what they mean.  It may sound like more work to do this, but if you try it, you will quickly find that understanding the reasons and the meaning actually makes everything easier.

Step 4: Never give up.

Math is hard.  Anyone who says otherwise is lying.  But you can do it anyway.  If you want to be good at anything, you have to stick with it, even when you feel like quitting.  You gain the most when you finally figure out a problem after a long struggle.  That's how you get smarter.  But you'll get nowhere if you give up whenever a problem is confusing or when you can't solve it right away.

Athletes know that working, fighting, against something that is hard makes you stronger.  The same goes for your brain--getting the right answer quickly won't make you smarter, but fighting with a hard problem for a long time will.

Step 5: Learn to read the textbook.

Math books are not like other books--they pack a lot of information into a small space.  One page might take you an hour to really understand well.  That is not because the books are poorly written--it is because it takes time to absorb the information, and you have to think carefully about every line.  You even have to think a lot about the pictures.

Most people who try to read math books get frustrated and give up--they expect the math book to be as easy to read as their favorite novel.  But if you slow down and really think about what is happening in each step, you will find that your book is like a personal tutor.  Most books have lots of examples and explain things in several different ways.  Most of them are written by someone who has been teaching for a long time and knows how to help you with the confusing parts.  Once you get the hang of reading them, they can make learning math a lot easier.

The one thing a book can't do is answer questions.  The great secret is read the book before you go to class.  Then you can ask the teacher about all the things that didn't make sense in the book.  Most people only try to read the book after class, when they didn't understand some part of what the teacher was saying.  But then if you have a question, you're stuck--you can't ask your questions because the teacher is gone.

Step 6: Talk to your teacher.

Professors and teachers want to help you.  Get to know them.  Go to them for help--they love to talk to students who want to learn.   Go to them to get help finding the right classes, to get help with homework (even for a class they are not teaching), and just to discuss life.  They can help you with your math, and they can help you avoid the mistakes they made when they were students.

Step 7: Look for the beauty.

Math is extremely useful, but it is also beautiful.  It connects lots of different ideas into one.  It explains important things that cannot be understood in any other way.  When you finally get it, it is exciting to see how things fit together, why things work, how it all makes sense.   Enjoy the experience of opening your mind.

facts about 2013.......

1. 2013 is composed of four different digits, and is the first such year since 1987.

2. 2013 is composed of four sequential digits, although obviously not in order. The last such year was nearly 600 years ago, back in 1432. But the next such year is only 18 years away.

3. 2013, 2014, and 2015 are consecutive years each of which is the product of three distinct primes (3 x 11 x 61, 2 x 19 x 53, and 5 x 13 x 31, respectively). The last such three-year sequence was back in 1885-1887, and the next one isn’t until 2665-2667.

4. As was 2012, 2013 is one of only 45 multi-digit numbers that, when spelled out in English, are alliterative (i.e., “two thousand thirteen”)

Mӧbius band.....

A Mӧbius band    (also called Mӧbius strip) is a one-sided surface that can be obtained by gluing two ends of a half-twisted long rectangular strip. They look cool in M.C. Escher’s drawings and in real life:

Mӧbius bands were independently discovered by German mathematician Johann Listing and German scholar August Ferdinand Mӧbius in the 1850s. Some interesting things about these shapes are as follows:

• If you draw a line down the middle of the strip, you will eventually reach the starting point after drawing on what appears to be both sides of the strip – proving that there really is only one side.
• By tracing one’s finger along the edge of a Mobius band, every possible point on the edge of the object will be touched – proving that the surface has only one edge.
• It is impossible to cut a Mobius band in half. If you cut a Mobius band along the centerline, you will end up with one long strip with two full twists, rather than two separate strips.
• The B.F. Goodrich Company utilized Mӧbius-like shapes to design conveyor belts. Because the “wear and tear” was distributed throughout the entire shape, these belts lasted twice as long as conventional belts.
• Mobius bands have been in the design of electronic resistors, compact resonators and superconductors for complex electrotechnology applications.

After years of searching for examples in natural materials, U.S. Department of Energy scientists have recently discovered Möbius-like shapes occurring in metamaterials – that is, materials engineered from artificial “atoms” and “molecules”. This is big news for scientists who want to create structures with shapes that aren’t naturally occurring in materials or molecules, and up to this point were limited to only mathematical imagination.

aint it cool?????????

Red-Black Card Trick.

Here's a pretty easy card trick that you can do that can also be pretty surprising. Here's how the trick you do will appear to others:

Take a deck of cards, and give it to a spectator and ask her to shuffle the deck and return it to you face down. You take the cards, and (with a little showmanship but without looking at the fronts of the cards) separate them into two piles, and then say "I've made two piles so that the number of red cards in the first pile is the number of black cards in the second pile."

Have your spectator turn over the cards and verify!

Presentation Suggestions:
Your spectator can shuffle the cards as many times as she likes--- it won't matter! When she gives the cards to you, all you are really doing (though don't make it obvious) is counting the cards into two piles so that there are 26 cards in each pile.

The Math Behind the Fact:
The reason this trick works is simple... if the number of red cards in the first and second piles is R and S, and the number of black cards in the first and second piles is A and B, then we know that R+S=26 (since the total number of red cards is 26) and S+B=26 (since the total number of cards in the second pile is 26). These two equations can be subtracted from one another to show that R-B=0, or R=B.

e (mathematical constant).

Ever think how the value of e comes out ,even after using many times in your daily maths routine.If you have and already know it, this post is not meant for you (plz check other posts),if not checkout this!!!!!!!!
e is a constant which is the limit of (1+(1/n))to the power n i.e.,the more you put value of n the more you get closer to its precise value......

or, in pure maths.,

The Kruskal Count....

Martin Kruskal, a Princeton physicist, discovered a strange mathematical property that appears to apply to all written text. Follow the steps listed below to discover this weird phenomenon.
Consider Steve Jobs’ famous commencement speech to Stanford University students in 2005:
Step 1: Select any word from any of the first ten words and count the number of letters in that word.
Step 2: Count that many words forward through the passage to land on a new word. (For example, if you chose “limited” in Step 1, count forward 7 words to “else’s”)
Step 3: Count the number of letters in the new word and move forward that many words.
Step 4: Repeat Steps 1 through 3 until there are not enough words to complete the last word count.
Step 5: Write down the last word on which you land.
No matter which word you use to start the steps, you will always land on the same word (In this case “to”). Weird, huh?

*verified by most of the text but still possibilities of exception 'may' be there.......not easy to find.......

maths in everyday life....

Math is a part of our lives, whether we clean the house, make supper or mow the lawn. Wherever you go, whatever you do, you are using math daily without even realizing it. It just comes naturally.

Chatting on the cell phone

Chatting on the cell phone is the way of communicating for most people nowadays. It's easy, accessible and cost effective. Every one has a cell phone and it requires a basic knowledge of skill and math. You need to know numbers and how they work, and with today's technology you can do basically everything on your cell phone, from talking and faxing to surfing the Internet.

In the kitchen

Baking and cooking requires some mathematical skill as well. Every ingredient has to be measured and sometimes you need to multiply or divide to get the exact amount you need. Whatever you do in the kitchen requires math. Even just using the stove is basic math skills in action.

Gardening

Even doing something as mundane as gardening requires a basic math skill. If you need to plant or sow new seeds or seedlings you need to make a row or count them out or even make holes. So even without thinking you are doing math. Measuring skills is always needed, and calculations of the essence when doing something new in the garden.

Arts

When doing any form of art you are using math. Whether you're a sculptor, a painter, a dancer or even just doing a collage for fun, you will need to be able to measure, count and apply basic math to it. Every form of art is co-dependant upon math skills.

Keeping a diary

Keeping a diary has become an essential part of our daily lives. We run from place to place and appointment to appointment. Making appointments and having a time schedule that works for you requires math. Without a diary we will crash and burn. Some people even have to make appointments to take some time out. Math is a much needed skill in today's life.

Planning an outing

Every outing you plan needs your math skill. Whether you go to the beach or the zoo is irrelevant. You will plan your way there and you will use your time wisely, math is your guide that will assist you and help you. When driving you need fuel, oil and water, without it your car will break down. All of these require math.

Banking

Can you imagine going to the bank and not having any idea what you need to do or how to manage your finances. This will cause a huge disaster in your life, and you will be bankrupt within hours.

Planning dinner parties

How about that inevitable dinner party or cocktail that you have to host. Planning is essential, how many guests are attending, what foods are you serving, the ambience of the place where you want to host it and so many other essentials all requiring multiplication, division and subtraction.

Decorating your home

Whether you are painting, doing the flooring or just acquiring new furniture, you need math to make your sums add up. Everything you do inside or outside of your home needs math skills. From accessories to a new swimming pool and putting in new lighting.

Statistics

Every basic thing we use in life consist of history. That means statistics. Taking into account the past and the future, and keeping record of what has been done. Without statistics we won't know what worked and what didn't. It helps us to find balance and structure.

maths behind google...

 The name of the popular search engine ‘Google’ came from a misspelling of the word ‘googol’, which is a very large number (the number one followed by one hundred zeros to be exact).

truely defined...

word math.

From number 0 to 1000, the letter ‘A’ only appears in 1000 (One thousand).

the dice fact....

The opposite sides of a dice always add up to 7.
