An easy trigo question

Answer 1

Is it E?

Answer 2

Looks like E

Answer 3

Yes. How did you get it?

Answer 4

Oh... I found my mistakes. Thanks all :(

Answer 5

We know that tan(45)=1 and raising it to a power, isn't going to change anything, so just find all ref. angles of 45 degrees.

Answer 6

I forgot the -1 when I tried it few months ago. Sorry!!!

Answer 7

\[\tan ^{2}\theta=1,-3\]
(After solving)
\[\tan ^{2}\theta=-3\] has no real solution.

So
\[\tan \theta=\pm 1\]
\[\theta=n \pi \pm 45\]
