Hi . Does anyone know of an easy way to remember:

d/dx sin x = cos x
d/dx cos x = -sin x
d/dx tan x = (sec^2)x
d/dx sec x = sec x tan x
d/dx cot x = (-csc^2)x
d/dx csc x = -csc x cot x

~Thanks

If you work with them ennough you will just memorize them anyway--- Also you could get all the other derivatives from just the quotient rule and the sin and cos properties.. so that might be the easiest way to do it.

Yes, just study them with the "flash card" type of study method. Just cover up the answer with your finger, see if you get it right, do it over and over, and try to engrave them into your memory.
