I think the best way to learn anything in a math course is by repitition. I have been a math tutor for nearly 11 years and the best advice I give students is to keep practicing problems. Do problems over and over again until the method becomes almost second nature.
If you do this you won't need to memorize any formulas. It will become something that you know. If you just want to know equations write them down over and over again.
Nothing gets into one's mind better than by writing it down. Reading them over and over helps some, but writing them has proven to be effective. Think about the concepts and try to understand them as well.
This can help if you tend to forget a formula. If you know how to differentiate, for example, but forget how to integrate, remember that integration is the opposite of differentiation and vice versa. Study all of the homework problems you have, along with your notes.
If you want, you can make flash cards with terms on one side an the formulas on the other side. That may help as well. Good luck!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
