Differentiation of Inverse Trigonometric Functions Each of the six basic trigonometric functions have corresponding inverse functions when appropriate restrictions are placed on the domain of the original functions. Since $\theta$ must be in the range of $\arcsin x$ (i.e., $[-\pi/2,\pi/2]$), we know $\cos \theta$ must be positive. Dividing both sides by $\sec^2 \theta$ immediately leads to a formula for the derivative. The differentiation of trigonometric functions is the mathematical process of finding the derivative of a trigonometric function, or its rate of change with respect to a variable. 11 mins.
