Simple Trignometry Problem to find radians

Trigonometric equation can be solved using trigonometric identities and find the value of x/radian/degree

Topic : Trigonometric Equation

In Trigonometric functions - Sine, Cosine's value are found as explained below.

Problem : Solve Sin x = Sin 2x and find x in degrees

Solution :
Sin x = Sin 2x
we have Sin 2x = 2 Sin x Cos x
So, Sin x = 2 Sin x Cos x
Sin x - 2 Sinx Cos x = 0
Sin x (1 - 2 Cos x) = 0
Sin x = 0 or 1 - 2 Cos x = 0
x = Sin^-1(0) and 1 = 2 Cos x ; Cos x = 1/2 ; x = Cos ^-1(1/2)
x = 0⁰ and x = 60⁰ =>first quadrant 360⁰ - 60⁰ = 300⁰ => fourth quadrant
So Solution is x = 0⁰ ; 60⁰ ; 300⁰

If required values can be converted into radians.
