Question

Find f''(x) of 3csc(x).
a) −3csc(x)cot(x)
b) 3csc(x)cot2(x)+3csc3(x)
c) 3csc2(x)cot(x)+3csc3(x)
d) 3csc(x)cot2(x)+3csc2(x)cot(x)
e) Does not exist.

Answer 1

guess you gotta take the derivative twice, no way around it

Answer 2

unfortunately

Answer 3

i know the trig derivatives, i just get confused with the -cscxcotx and then taking the derivative of that

Answer 4

first time you get
\[f'(x)=-3\csc(x)\cot(x)\] now it is a product rule problem

Answer 5

oh, duh. didnt even think about the product rule. Ill see if i can do it now.

Answer 6

lol it is not like you have a choice!

Answer 7

I know! I spaced...

Answer 8

btw i got b as my answer
