Solve the equation sin2x = 3cos2x. the value of x that satisfies the equation if x lies in the second quadrant is °. the value of x that satisfies the equation if x lies in the third quadrant is °.

and

respectively.

Step-by-step explanation:

The given trigonometric equation is

We divide both sides by to get,

This implies that,

We take the inverse tangent of both sides to get,

Since the tangent ratio has a period of , another solution is

to the nearest degree.

In the third quadrant,

The solutions are

The value of x that satisfies the equation if x lies in the second quadrant is

The value of x that satisfies the equation if x lies in the third quadrant is
