Question

solve for x
tan^2x=1/3

Answer 1

x=15

Answer 2

the original equation was
\[3\sin ^{2}x= \cos ^{2}x, 0\le x < 2\pi\]

Answer 3

its correct.
x=15

Answer 4

and I divided the whole thing by \[\cos ^{2}x\] to get \[3\tan ^{2}x =1\]

Answer 5

I just don't understand how you are getting 15

Answer 6

i am pretty sure the directions want the answer to be in radians.
