For most maths exams the required formulae are given with paper! especially the ones that are hard to memorize but if you are not provided with anything like that, there are few ways to remember: The best way for me is writing them down on papers and pasting on walls where I see them regularly. Or you could find and practice the formulae derivation from the beginning, so that even in an exam you could derive the whole thing from scrap if you forget! Hope that helps! Good Luck!

i never had a formula written in any of maths question paper i had.. i have passed 5 mathematical papers of anna university...i never had a hint or a stream of formula in any of the question papers... the toughest mathematical paper is probability random processes ... more formulas is numerical methods of anna university..

Where is Anna University? Well, if you know about the British education system you will know that most of the formulae are given because we Engineers are not there to memorize stuff, instead we apply and get things done. Cheers!

What kind of math problems are you trying to remember. There are little acronyms that you can use like PEMDAS for parentheses, exponents, multiplication, division, adding and subtraction.

When I teach that one to young children, I tell them to remember "Please Excuse My Dear Aunt Sally" but I notice most adults just remember PEMDAS, although for children that makes no sense because it's not an actual word.

well as my instructor said. constant practice is the best solution to that. you need to use it every time so as to memorize them. and also you need to know and understand the derivation.

as an engineering student, i memorize formulas by practicing and using it into application. if you really do not know how to use them then it is useless to memorize them. one thi ng more is you need to understand what are you doing. if they say square root, what is square root? you have to understand what are you dealing with. many people think that math is hard and will make you sick but not. math is fun and you need it in your daily life. actually you are dealing with math daily but you do not know.

To remember the maths, you must train with a formula in the paper and write some numbers to try without need to see notes. This will works for me, but i hope it can help you remember the maths formulas.

For me, it depends which ones. I come up with silly things to remember them by. Like in trig for the csc and cot vertical asymptotes the equation is x = (pi)k, but for the sec and tan vertical asymptotes the equation is x = 1/2(pi) + (pi)k. I can always remember the two equations, but I used to mix up what they were for. I finally came up with that the cosecant and cotangent start with the letter "c" which is before the letters "s" and "t" for secant and tangent and so to me I can think of that being associated with a shorter formula. I used to do math tutoring and for kids I'd come up with silly little saying and stuff. And then for adults I found most people can remember something that sounds vaguely, umm, dirty. So if you can somehow associate the formula with something dirty or even just party like, it seems like that helps a lot of people. For example, this is one I got from a math teacher for the quadratic formula: "The negative Boy couldn't decide (+/- sign) to go to the Radical party or B Square and miss out (-) on 4 Awesome Chicks, but it was all over at 2 A.m." Hope that helps!

i know wat u mean. as with most learnings,part of math is about recallin the of the game. I generally used the old school approach and write out the formula about 100 times. However, I think a better approach is to try to learn the derivation of each formula. I think if you intuitively know why/how the formula works, you can try to derive it on the spot if you forget the structure. The only problem with this approach is it may take you an extra few minutes,therefore,you are now under more time pressure when taking a quiz.

Whenever you come across a formula , you jot it down in a seperate notebook. You should read twice or thrice . Recall it. Before going to exam or test , just go through the written formulae. It will stick to your mind . Taking notes is a good way to improve memory . As said by previous members , whenever you are using the formula in problems makes your mind more familiar .

Hi, Tk5013! Well, if you find difficulty in memorizing many formulas, you must learn how to derive. When you know how to derive, you do not have to memorize all different formulas with same variables. Instead, you only memorize the basic formula then derive if required. I hope this might help, happy mylotting...=)

the best way is to solve more problems on the formulas..this will lead u to remember the formulas...last semester i had numerical methods mathematical paper..this contains only formulas to remember and to substitute..so u have to solve more problems based on the formulas.. naturally integration and differentiation requires more attention on solving more problems.. probability just think and solve,,its just like gambling requires more mathematical skills..

The best thing you can do is to practice those formulas all the time. Create acronyms if you can so that you can easily recall the formulas. Remember the simple MDAS code, it is a great acronym code when solving a simple Algebra that involves different operation.

I find that the best way is to write out the equation several times. This way you get used to writing out the equation. I also verbally say the equation while writing it, I was really suprised how much it can stick into your head. This method definetly works for me and I hope it works for you. Goodluck!
