Let h (x) = x and g (x) = arcsin x, function f is considered as the product Don't show me this again. Practice example to know more about the topic. 8 #1-73 odds Since all trigonometric functions are 2ˇ-periodic, they are not one-to-one. 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. e. These inverse functions in trigonometry are used to get the The basic trigonometric functions include the following 6 functions: sine (sinx), cosine (cosx), tangent (tanx), cotangent (cotx), secant (secx) and cosecant (cscx). And similarly for each of the inverse trigonometric functions. In this section, we are going to look at the derivatives of the inverse trigonometric functions  Inverse. To find the derivative of arcsinx, first think of it as y= arcsin x. 1 3. For example, a linear function that has a slope of 4 has an inverse function with a slope of 1 ⁄ 4.
