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. WebIn mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled …
