Here's a little trick for remembering those pesky math formulas. Write them out on a notecard and tape it to the UPPER LEFT CORNER of the mirror you use every day to brush your teeth, style your hair, and admire your countenance. You'll find yourself glancing at it, but don't make it an effort. When looking for a particular formula in your brain, move your eyes UP AND LEFT. Is the notecard there?
If this subtle method does not work for you, if you don't "picture" the card when it isn't physically in front of you, try the next step. Add a little picture to the formula to give yourself another visual clue.
Still having trouble? Try "hearing" the music of a formula. You're probably familiar with the rhythm of (A squared plus B squared equals C squared). Pick a different formula each day and say it in your mind several times while you're doing those mirror tasks.
Whenever I'm working a problem, I first write down the applicable formula. That makes even tough problems nothing more than a matter of substitution and calculation.
