Answer 4

use ~ as a space in equation editor.

Answer 5

sry its not sin its sec instead of sin at both the places

Answer 6

\[Cosθ+Secθ=2~~~~~~then~~~~~~Cos^2θ+Sec^2θ=~?~~~~~~~~~~~~THIS?\]

Answer 7

yes plz answer

Answer 8

\[Cosθ+\frac{1}{Cosθ} =2\]can you find

Cosθ

Answer 9

PLIZ LET HER TRY!

Answer 10

square 1st eqn both sides and cos.sec =1..

Answer 11

I suggest you substitute x=cos(theta) if that helps make you more comfortable.
