['To find an inverse function reflect a graph of a function across the y=x line and find the resulting equation. This can also be done by setting y=x and x=y. ... ', 'now switch the x and y variables to create the inverse functions. ... ', 'This function when solved for y will be the same as the following.']

One way to work out an inverse function is to reverse the operations that f carries out on a number. Here is a simple example. We shall set f(x)=4x, so that f takes a number x and multiplies it by 4: f(x)=4x (multiply by 4). (divide by 4).

For example, find the inverse of f(x)=3x+2. Inverse functions, in the most general sense, are functions that "reverse" each other. For example, if f takes a to b, then the inverse, f − 1 f^{-1} f−1f, start superscript, minus, 1, end superscript, must take b to a.

Desmos can operation in radians or degrees, this is set from the coordinates dialog box available via the monkey wrench icon. Desmos also has a scientific calculator that can be set in degrees or radians. This is a scientific calculator on the same steroids as Desmos' graphing calculator.

To find the roots of the equation, replace y with 0 and solve. Rewrite the equation as cos(x)=0 cos ( x ) = 0 . Take the inverse cosine of both sides of the equation to extract x from inside the cosine. The exact value of arccos(0) is π2 .

Key Steps in Finding the Inverse Function of a Rational Function. Replace f ( x ) f\left( x \right) f(x) by y. Switch the roles of x and y, in other words, interchange x and y in the equation.

Graph an Inverse Function. Summary: After you graph a function on your TI-83/84, you can make a picture of its inverse by using the DrawInv command on the DRAW menu. For this illustration, let's use f(x) = √(x−2), shown at right.

Given a function, say f(x), to find the inverse of the function, we first change f(x) to y. Next, we change all x to y and y to x. and then we solve for y. The obtained solution for y is the inverse of the original function.

We will learn how to prove the property of the inverse trigonometric function 2 cos−1 x = cos−1 (2x2 - 1) or, 2 arccos(x) = arccos(2x2 - 1).

The domain of the inverse tangent function is (−∞,∞) and the range is (−π2,π2) . The inverse of the tangent function will yield values in the 1st and 4th quadrants. The same process is used to find the inverse functions for the remaining trigonometric functions--cotangent, secant and cosecant.

The inverse of a function is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function. In plain English, finding an inverse is simply the swapping of the x and y coordinates.
