INVERSE TRIGONOMETRIC FUNCTIONS

Step 1: Identify the inverse function we need to use. Since the equation we're given involves the sine of an angle θ θ, Step 2: Input sin−1( √2 2) sin − 1 ( 2 2) into your calculator, making sure

Inverse Trigonometric Functions

Inverse Cosine Examples Example 1: Determine the value of x if cos -1 (√3/2) = x using the inverse cosine formula. Solution: We have cos x = Example 2: Evaluate cos (cos -1 5) and cos -1 (cos 5π/3) using inverse cosine properties. Solution: First we will
