WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. 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.
