The domains of the other trigonometric functions are restricted appropriately, so that they become one-to-one functions and their inverse can be determined. Dividing both sides by $\sec^2 \theta$ immediately leads to a formula for the derivative. The derivatives of inverse trigonometric functions are quite surprising in that their derivatives are actually algebraic functions. Click or tap a problem to see the solution. In both, the product of $\sec \theta \tan \theta$ must be positive. Sec 3.8 Derivatives of Inverse Functions and Inverse Trigonometric Functions Ex 1 Let f x( )= x5 + 2x −1. One way to do this that is particularly helpful in understanding how these derivatives are obtained is to use a combination of implicit differentiation and right triangles. For example, the derivative of the sine function is written sin′ = cos, meaning that the rate of change of sin at a particular angle x = a is given by the cosine of that angle. Trigonometric Functions (With Restricted Domains) and Their Inverses. Check out all of our online calculators here! Formula for the Derivative of Inverse Cosecant Function.

These six important functions are used to find the angle measure in a right triangle when two sides of the triangle measures are known. 7 mins. The inverse sine function (Arcsin), y = arcsin x, is the inverse of the sine function. Inverse Sine Function. Since $\theta$ must be in the range of $\arcsin x$ (i.e., $[-\pi/2,\pi/2]$), we know $\cos \theta$ must be positive. Here, we suppose $\textrm{arcsec } x = \theta$, which means $sec \theta = x$. Thus, Finally, plugging this into our formula for the derivative of $\arccos x$, we find, Finding the Derivative of the Inverse Tangent Function, $\displaystyle{\frac{d}{dx} (\arctan x)}$. To be a useful formula for the derivative of $\arccos x$ however, we would prefer that $\displaystyle{\frac{d\theta}{dx} = \frac{d}{dx} (\arccos x)}$ be expressed in terms of $x$, not $\theta$. You can think of them as opposites; In a way, the two functions “undo” each other. VIEW MORE. Like before, we differentiate this implicitly with respect to $x$ to find, Solving for $d\theta/dx$ in terms of $\theta$ we quickly get, This is where we need to be careful.
