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:
Divide throughout the equation by
Simplify fraction throughout the equation
Solving the equation and finding x values that makes it true in the interval
- By subtracting 1 on both sides of the equation
- By simplify on both sides of the equation
- By dividing -1 on both sides of the equation
- By simplifying fraction on both sides of the equation
