WebThe Pythagorean identities are a set of trigonometric identities that are based on the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. The most common Pythagorean identities are: sin²x + cos²x = 1 1 + tan²x = sec²x. WebSolved Examples on Trigonometric Functions Example 1: Find the values of Sin 45°, Cos 60° and Tan 60°. Solution: Using the trigonometric table, we have Sin 45° = 1/√2 Cos 60° = 1/2 Tan 60° = √3 Example 2: Evaluate Sin …
