Example: If sinθ = x, then we can write θ = sin-1x. This returns the angle for which the sine value of the angle is x. Similarly, there exists cos -1 θ, tan -1 θ, cot -1 θ, sec -1 θ, and cosec -1 θ Sample Problems
WebMar 4, 2024 · Find an angle given two sides of a right triangle. Sometimes an angle that has a particular trigonometric ratio is desired. In this situation we use the inverse trigonometric functions sin − 1, cos − 1, and tan − 1 on a calculator to find an angle with a given trigonometric ratio. Example 5.2.7
These are the four steps we need to follow: 1. Step 1Find which two sides we know – out of Opposite, Adjacent and Hypotenuse. 2.
