Pythagorean theaorem basically a theorem relating three sides of a triangle.This relation becomes the very basic trigonometric identity and it is almost used in all trigometric computations.This online calculator makes your calculations very easier. enter the required angle as input and get the results at instants.

### Trig pythagorean identities

Pythagorean trigonometric identity states that, If the length of the hypotenuse of a right triangle is 1, then the lengths of the legs are the sine and cosine of one of the angles.

Pythagorean trigonometric identities:

sin2θ + cos2 = 1

tan2θ + 1 = sec2θ

1 + cot2θ = cosec2θ
