Question

I NEED HELP HURRY PLEASE, THANKS! :)

Thanks! I hope my answer would be easy to understand.

Answer 2

Answer:
`\bold{b)\quad (\pi)/(2)+n\pi,\ (\pi)/(4)+2n\pi}`

Explanation:

cos x tan x - cos x = 0

cos x (tan x - 1) = 0

cos x = 0 tan x - 1 = 0

`x=(\pi)/(2),\ (3\pi)/(2)` tan x = 1

`x=(\pi)/(4),\ (5\pi)/(4)`
