Where does Pythagorean identities and also how it relates to the right triangles
Ostrovityanka [42]

Answer:

A pythagorean identity means that for any angle \theta, sin^2\theta+cos^2\theta=1.

This also means 1+tan^2\theta=sec^2\theta \mbox{ and } 1+cot^2\theta=csc^2\theta. The symbol, theta (\theta) represents one of the acute angles in the right triangle. The hypotenuse (familiarly c in the regular pythagorean theorem) is 1. The triangle base is cos\theta, and the height (side perpendicular to the base, making a right angle) is sin\theta. The angle theta is opposite the sin\theta side.

Step-by-step explanation:

The pythagorean theorem applies to right triangles, which always have a 90 degree angle. Pythagorean identities are used to simplify trigonometric expressions/evaluate trig functions and to find the trig ratios in a right triangle.
