Inverse Trigonometric Function Formulas: While studying calculus we see that Inverse trigonometric function plays a very important role. For example, the inverse function for the sine, known as the inverse sine (sin−1) or arcsine (arcsin or asin), satisfies and This article uses the notation below for inverse trigonometric functions: Functionsin cos tan … The inverse trigonometric functions actually performs the opposite operation of the trigonometric functions such as sine, cosine, tangent, cosecant, secant, and cotangent. Their usual abbreviations are sin(θ), cos(θ) and tan(θ), respectively, where θ denotes the angle. For example, if we restrict the domain of sinxto the interval − ˇ 2; ˇ 2 we have a one-to-one function which has an inverse denoted by arcsinx or sin−1 x.

The other functions are similar. %PDF-1.4 >>stream c. Basically, they are the trig reciprocal identities of sin, cos, tan and other functions. of sin−1 x, the function cos−1 xoccurs explicitly in very few formulas. << Here, the domain of g = range of fand the range of g= domain of f. The function gis called the inverse of f and is denoted by f–1. These are the inverse functions of the trigonometric functions with suitably restricted domains.Specifically, they are the inverse functions of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle’s trigonometric ratios. If f and g are two functions such that f(g(x)) = x for every x in the domain of g, and, g(f(x)) = x , for every x in the domain of f, then, f and g are inverse functions of each other. The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.
