Solution We can use a method similar to the one used to solve Example 1.8 in Section 1.2. That is, draw a right triangle and interpret cos θ as the ratio adjacent hypotenuse of two of its sides. Since cos θ = − 4 5, we can use 4 as the length of the adjacent side and 5 as the length of the hypotenuse.

WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebFinding the Exact Value of Expressions Involving the Inverse Sine, Cosine, and Tangent Functions Now that we can identify inverse functions, we will learn to evaluate them.
