Question

are there any fun or good ways to remember the derivatives of the trig functions. im getting tired of doing the quotient rule for them and i dont want to spend time memorizing them either

Answer 1

Practice, practice, (practice)^10.

Answer 2

thats aids no thanks

Answer 3

@nuts u got anything good?

Answer 4

I thought.. you were looking for *Good Ways*. never mind

Answer 5

im talking about mnemonics

Answer 6

or patterns

Answer 7

even limited to the sin & cos relationship, there are patterns that you can try and put in some box, but good luck with that:

- cos is even, sin is odd

- d(cos) = - sin, d(sin) = +cos

- best fact --> they are the SAME thing with a pi/2 phase shift

- so periodicity means they are essentially the same thing, right?

and if you're getting "tired" of elementary math, you belong to an exclusive club that doesn't include anyone who is actually any good at math.

sheesh :(

Answer 8

@Shadow look at this lol

Answer 10

Dear noob i mean friend,
there is a way after looking around i figured out if you align sec sec tan and -csc csc cot you cover up which f' u want to find and u get the derivative. wanna find f' of tan well sec*sec is sec^2(x). wanna find csc well cover csc up and u get -csc*cot LOLOLOL this is way easier than using any of that bs u just tried to get me to do. respectfully, Gabriel

Answer 11

makes no sense at all.

Answer 12

makes perfect sense but maybe rows and columns just arent ur thing i get that
