Thread: Improving math calculations ability

Actually yes, when I was learning stuff like sin^2+cos^2=1, I memorized it in that form. Same with the others. It makes spotting them in equations, or using them far easier. I think you are misunderstanding, in that I said you are suppose to learn how it works first. So your not memorizing anything you don't already understand. You are memorizing stuff you already know, so you can do it a lot faster, and more accurately.

In the originally post, he already said he knew how to do it, he just wanted to increase his speed. In all the examples you give, if you have to figure the stuff out it is going to take multiple steps, and if their multiples of them in a problem it will take you forever. If your adding an extra 30 steps in a problem, it doesn't matter how easy those steps are, its going to make it take a lot longer to do.

You want to be reducing the steps you need to take, not adding steps. By memorizing the formulas and understanding how they work you reduce your time by a great deal. I am actually surprised that you think you can do high level math without knowing any formulas at all. My guess is that you probably do really know them.

You don't get permanently faster by sitting down and memorizing some formulas. You get faster by solving a ton of exercises so that it sticks to memory by itself.
