Inverse Sine Function (arcsin x sin1x) The trigonometric function sin x is notWe see from the graph of the restricted sine function (or from its derivative) that the function is one-to-one and hence has an inverse, shown in red in the diagram below.and one can use this to prove that. derivatives of trigonometric functions, basic. involving inverse trigonometric parts.Proof. This time I will show you how to prove the formula for y cos-1 x . Before we start, let me remind you that the domain of this function is. The derivatives of inverse sine , inverse cos , inverse tan , inverse csc , inverse sec , inverse cot functions are given belowNow using the trigonometric formula, Now as , sin y x. Thus , Derivative of inverse cos function But for negative x, some people dene sec1 x to be the number between and 3/2 whose secant is x.

Under this denition, the derivative of sec1 x turns out to be 1/(x x2 1). 7 Integrating the Inverse Trigonometric Functions. 3.1 Derivatives of inverse trigonometric functions. 3.2 Expression as definite integrals. 3.3 Infinite series. 3.3.1 Variant: Continued fractions for arctangent.The Pythagorean theorem was known long before Pythagoras, but he may well have been the first to prove it, in any event, the proof attributed to These derivatives will prove invaluable in the study of integration later in this text.
