y=tan−1xy=tan−1x has domain (−∞, ∞) and range (−π2, π2)(−π2, π2)The graphs of the inverse functions are shown in Figure 4, Figure 5, and Figure 6. Notice that the output of each of these inverse functions is a number, an angle in radian measure. We...
To find the derivative of arcsin x, let us assume that y = arcsin x. Then by the definition of inverse sine, sin y = x. Differentiating both sides with respect to x,cos y (dy/dx) = 1dy/dx = 1/cos y ... (1)By one of the trigonometric identities, sin2y + cos2y = 1. ...
