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. WebSee Inverse trigonometric functions. On calculators and spreadsheets, the inverse functions are sometimes written acos(x) or cos-1 (x). Trigonometry functions of large and/or negative angles. The six functions can also be defined in a rectangular coordinate system. This allows them to go beyond right triangles, to where the angles can have any ...
