# Inverse Function Calculator

**Looking for an inverse function calculator?** Use this one:

Calculators have been in use for centuries now, for both schooling systems and serious professional calculations.

In the past, only physical calculators were available for use. However, with the advent of technology, programmers have developed online calculators as well. These are wonderful tools that offer a number of advantages over traditional physical calculators.

For example, they are straightforward to use, provide very precise and accurate results, and even offer suggestions to help you simplify the calculations involved. They can also help you do calculations that could be quite difficult for other kinds of calculators. This is very useful if you are in a tricky situation that demands pinpoint precision.

To use an online calculator, all you require is access to the internet and a device that can connect to the internet. Most companies provide online calculators for free, and thus they are being used by a lot of people on a daily basis. For professionals in any field, online calculators can save energy and time and increase efficiency in their workplace as well. One such helpful online calculator is the inverse function calculator, which can compute the inverse value of any function that is provided as an input. In this article, I will explain what an inverse function is and how it can be calculated with the help of the inverse function calculator.

## What is an inverse function?

An inverse function, also known as an anti-function, is defined as a function that is capable of reversing into another function. In other words, it is a function that returns the original value for which a function has given the output.

Basically, if a given function “f” takes x to y, then the inverse of the function “f” will take y to x. If the original function is denoted by “f” or “F”, then the inverse function will be denoted by f^{-1} or F^{-1}. Remember, though, that you must not confuse (-1) with reciprocal or exponent over here.

If f and g happen to be inverse functions, then f(x)=y only if g(y)=x.

## Inverse Functions in Trigonometry

In trigonometry, the inverse sine function is used to find out the measure of the angle for which the sine function generated the value. For example, let’s say we need to find the inverse of the trigonometrical function sin x= ½. In this case, the value of x is equal to the angle, the sine function of which is ½.

We know that sin 30°=½.

Thus, sin x = ½

x=sin-1(½) = sin-1(sin 30°) = 30°

## How to find the inverse of a function (step by step)?

In order to find the inverse of a function, you must first replace the function variable with the other variable. After that, you need to solve for the other variable by replacing both of them.

For example, let’s say you need to find the inverse of f(x) = y = 3x – 2

- First of all, replace f(x) with f(y). The equation y = 3x – 2 will now become x = 3y - 2.
- Solving for y, it is found that 1/y = (x+2)/3.
- This is the inverse of the equation y = 3x – 2.

## How to use the inverse function calculator?

The inverse function calculator is one of the easiest online tools to use. You simply need to follow the steps given below:

- First of all, enter the function to be solved in the input box (across the text which reads “the inverse function).
- Click the “Submit” button at the lower portion of the calculator window.
- Soon, a new window will open up and the inverse of the function you entered will be calculated in there.

## Conclusion

The inverse function calculator is a simple and useful tool that can perform the calculation with great speed and accuracy. I hope you find it helpful whether you are a student, teacher, engineer, or professional mathematician.
