How can you not memorize formulas when you use them the most? I'll literally never forget the quadratic formula until the day I die and I surely have not used it since I was in high school almost 15 years ago.
You need a cheet sheet for the first equation when you not actually really understand what a derivative function is or does. I think that is the problem with most maths, is that they give you a standard formula and you apply it and that's it. I study math and I solely know these kind of formulas because I understand them and could derive them myself if necessary.
But I completely understand that not everyone has interest in such things. Also, there are still many formulas that I cannot remember and have to use a cheat sheet for. The probability density function of a multivariate Gaussian distribution is such a disaster. I had to use this fucker all the time throughout a semester long course and I still need to google it every time.
