Find all solutions on the interval (0,2pi)
12tan^2(x)=4
12tan%5E2%28x%29=4
tan%5E2%28x%29=4%2F12=1%2F3
tanx=±√(3)/3
x=π/3, 2π/3, 4π/3, 5π/3

~~~~~~~~~~~~~~~~~~~~~~


        In the post by @lwsshak3, the values of angles in the answer are determined INCORRECTLY.
        I came to bring a correct solution.


12tan^2(x)=4
12tan^2(x) = 4
tan^2(x) = 4%2F12 = 1%2F3
tan(x) = +/- sqrt%283%29%2F3
x =  pi%2F6,  5pi%2F6,  7pi%2F6,  11pi%2F6.         ANSWER

After checking many solutions by @lwsshak3, I see that his level in Trigonometry
is lower than in other topics. He makes errors in this area which a professional tutor
should not make.
