In mathematics the inverse trigonometric functions occasionally also called antitrigonometric 1 cyclometric 2 or arcus functions 3 are the inverse functions of the trigonometric functions Arctan 1 or tan inverse 1 gives the angle measure of a right angled triangle in which the ratio of the opposite side and the adjacent side to the angle is equal to 1 The value of arctan 1 is 45 or 4 radians
