Question

I'm stuck half way on a derivative help. How do I simplify this cscx(cot^2x+csc^2x)

Answer 1

what was the original derivative?

Answer 2

cscx...its the second derv

Answer 3

So you are trying to find the original function?

Answer 4

no. i found the first derv, then the second, but the book has 2csc^3 x -cscx as the answer for the second and i have cscx(cot^2x+csc^2x) ...how do i get from where i am to where to book is

Answer 5

alright i got it. i am going to write down the steps right quick.

Answer 6

ok thx

Answer 7

let me know if you cant read it.

Answer 8

yes thats what i go, how do i simplify it further

Answer 9

I think your book may have the wrong answer for that one.

Answer 10

it shows that it turned the cot^2x into csc^2x -1

Answer 11

would your teacher not take the answer you got?

Answer 12

idk. my professor wont let me email him bc hes busy so idk

Answer 13

I think your professor would worry more about you being able to do the actual calculus derivation rather than being able to simplify it to what the book is. At least my professor did anyways.

Answer 14

every time i try to simplify it, it keeps getting bigger than it was originally.

Answer 15

oh ok
