solutions to the equation tan^2x - 3 = 0 ( there can be more than one)

2pi/3

pi

-pi/3

5pi/3

1 answer

There are in fact an infinite number of solutions
I would try each of the choices
I have my calculator set on degrees so 2pi = 360

tan^2 (360/3 ) = 3 Yes that works
tan 180 does not work
tan -60 does not work
tan 300 = nope
so only A
