Question

find the second derivative if y=6cscx

I need help finding the second derivative. I believe that the 1st derivative is -6(cscxcotx)

Could you help me find the 2nd step by step.

Answer 1

what is the first derivative of it?

Answer 2

I am not sure but I think that it is -6cscxcotx.
The problem gave me the function y=6cscx and just asked me to find the second derivative

Answer 3

ok, you are right., so, y' = -6 csc (x) cot x
y" = (-6 csc (x) cot x)' just apply product rule, what is hard?

Answer 4

Okay would it be:
-6[(cscx)(-csc^2x)+(cotx)(-cotxcscx) = 6csc^3x+(6cot^2x)(cscx)
I am unsure of what to do with the -6

Answer 6

I am lazy to figure out, you read it by yourself http://www.wolframalpha.com/input/?i=%286csc+x%29%22

Answer 7

ummmm okay thanks for your help

Answer 8

don't want it? hehehe... I am sorry,

Answer 9

you want me here to guide you step by step? it waste, friend, short answer for 6: if you want , treat it as a variable and take derivative of it (=0) . or treat it as a constant, let it at very first position, then [ calculate here....] then time it back to term by term in the bracket
