The inverse trigonometric functions are the inverse functions of the y=sin x, y=cos x, and y=tan x functions restricted to appropriate domains. If the argument has the structure or , and or with integer , the tangent function can be automatically transformed into trigonometric or hyperbolic tangent or cotangent functions. 3. The effect of flipping the graph about the line y=x y = x is to swap the roles of x x and y y, so this observation is true for the graph of any inverse function. They are also termed arcus functions, antitrigonometric functions or cyclometric functions.

Most scientific calculators and calculator-emulating applications have specific keys or buttons for the inverse sine, cosine, and tangent functions. x = f (y) x = f ( y). Unit 8 Absolute value equations, functions, & inequalities. The inverse tangent is one of the inverse trigonometric functions. The inverse of Tangent is represented by arctan or tan -1. The trigonometric functions/ratios are: Sine Cosine Tangent Secant Cosecant Cotangent The inverse of these trigonometric functions are as follows: inverse sine -1 The inverse tan of 1, ie tan -1 (1) is a very special value for the inverse tangent function.
