Question

Simplify \(\frac{cos^{2}a}{1-tana} + \frac{sin^{2}a}{1-cota}\)

Answer 1

I saw you post it twice, I will guide you how to do, but you WORK, not me, OK?

Answer 2

yeah

Answer 3

break it down, the first term: I let a aside because all of them respect to a, right?
\[\dfrac{cos^2}{1-tan}=\dfrac{cos^2}{1-\dfrac{sin}{cos}}\] .Simplify it, what do you get?

Answer 4

thank you :) I've solved it

Answer 5

ok, good luck
