Quick background: Community college student with quite a love for philosophy, mathematics, history, and politics. I'll be transferring to a four-year institution next year to complete my undergraduate degree (undecided major, but leaning towards a double or possibly even triple major in those fields above). I am by no means stellar at any of those fields per se, but simply enjoy them greatly and get good grades in them. One question I have concerning mathematics is whether or not memorization of formulas is something that is absolutely necessary for either an undergraduate degree in it or possibly a career using applied maths? I find myself frequently having to look up formulas or rules for certain mathematical operations (if I haven't used them in a few months), despite having aced exams using them in the past. I possibly have a bad math formula and rules memory, but can recognize the big picture and what to do in mathematical problems to find solutions (despite forgetting formulas). Are there those who've gone on to successfully complete a math undergraduate degree/minor or a career using applied maths, who have memorization problems like this? Also, in the "real" work world, is it feasible to take a quick break to look up a math formula or rule of some sort to solve a problem? Or, would that be embarrassing and/or indicate too low of a level of proficiency to be effective in the work force? Appreciate your thoughts in advance!
