Question

cot x sec^4x - cot x + 2 tan x + tan^3 x

Answer 1

Do you want to factorize this?

Answer 2

Answer 3

I think so. I'm confused on how to get this answer

Answer 4

I know we're suppose to prove the identity and set it up by using sin^2t + cos^2=1

Answer 5

and actually in the place of t we are using theta

Answer 6

what identity are you proving?

Answer 7

cot x sec^4 x =cot x +2 tan x + tan3 x

Answer 8

that should be tan^3x on the end

Answer 9

divide through by cotx

left side is then sec^2 x*sec^2 x =(tan^2 x +1)(tan^2 x +1)
right side is 1 +2tan^2 x +tan^4 x

Answer 10

factor the right side.

Answer 11

ok I'm going to try this now.

Answer 12

I'm still a little loss but I'm trying to figure this out out. ugh
