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:
Factor the Greatest Common Factor from left side of the equation
Using the zero factor property which states that if
Solving the 1st equation and finding x values that makes it true in the interval
- By dividing 2 on both sides
- By simplifying fraction on both sides of the equation
Solving the 2nd equation and finding x values that makes it true in the interval
- By subtracting1 on both sides of the equation
- By simplifying on both sides of the equation
- By dividing -2 on both sides of the equation
- By simplifying fraction on both sides of the equation
