How to solve trigonometric equation with tangent

The video tutorial explains how to solve the equation 3*tan^2(x) - 1 = 0 over the interval 0 to 2π. It begins by simplifying the equation using inverse operations, similar to algebraic methods. The tutorial then focuses on finding the values of X that satisfy the equation by using the unit circle. The instructor identifies key angles where the tangent value equals ±√3/3, specifically at π/6, 5π/6, 7π/6, and 11π/6. The lesson concludes by summarizing the solutions found within one revolution of the unit circle.
