Given information : Function
Concept Involved:
Solution to a
To solve a trigonometric equation, use standard algebraic techniques (when possible) such as collecting like terms, extracting square roots, and factoring.
Our preliminary goal in solving a trigonometric equation is to isolate the trigonometric function on one side of the equation.
Calculation:
Use the double angle identity to rewrite the left side of the equation
Take inverse on both sides
Simplify on both sides
Multiplying ½ to get the values of x in the interval
