What are all the exact solutions of -3tan^2(x)+1=0? give your answer in radians.

and

Step-by-step explanation:

The given equation is

Subtract 1 on both sides, we get

Divide -3 on both sides, we get

Taking square root on both sides, we get

We know that

Thus, when

When  

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
