Question

Which of the following are solutions to (2tanx)/(1 - tan^2x) = √3 ? Check all that apply.

Answer 1

A. x = 5π/6 + nπ
B. x = π/3 + nπ
C. x = π/6 + nπ
D. x = 2π/3 + nπ

Answer 2

(2tanx)/(1 - tan^2x) =tan 2x

Answer 3

Can you do it now

Answer 4

Is that not an identity?

Answer 5

Yes.

Answer 6

But it can't be all of them, right...

Answer 7

It cant be all of them. tan 2x=root(3)

Solve for x

Answer 8

From what I've got, its only C.

Answer 9

You are right

Answer 10

C and D
