The Integral Calculator lets you calculate integrals and also antiderivatives of functions online — because that free!

Our calculator allows you to examine your remedies to calculus exercises. It help you practice by reflecting you the complete working (step by action integration). All usual integration techniques and even special features are supported.

You are watching: Antiderivative of e^x^2

The Integral Calculator support definite and indefinite integrals (antiderivatives) and integrating features with numerous variables. Girlfriend can likewise check your answers! interactive graphs/plots help visualize and much better understand the functions.

For more about how to use the Integral Calculator, go to "Help" or take a look at the examples.

And now: Happy integrating!

Enter the role you desire to integrate into the Integral Calculator. Skip the "f(x) =" part and the differential "dx"! The Integral Calculator will show you a graphical variation of her input while you type. Make certain that it shows exactly what girlfriend want. Usage parentheses, if necessary, e.g. "a/(b+c)".

In "Examples", you deserve to see which features are supported by the Integral Calculator and how to use them.

When you"re excellent entering her function, click "Go!", and also the Integral Calculator will display the an outcome below.

In "Options", girlfriend can collection the variable of integration and also the integration bounds. If you don"t specify the bounds, just the antiderivative will certainly be computed.

Clicking an example enters it right into the Integral Calculator. Relocating the mouse over it shows the text.

How the Integral Calculator Works

For those v a technical background, the complying with section describes how the Integral Calculator works.

First, a parser analyzes the math function. That transforms it right into a type that is far better understandable by a computer, namely a tree (see number below). In doing this, the Integral Calculator needs to respect the stimulate of operations. A specialty in mathematical expressions is that the multiplication sign have the right to be left out sometimes, for example we write "5x" rather of "5*x". The Integral Calculator has to detect this cases and also insert the multiplication sign.

The parser is applied in JavaScript, based upon the Shunting-yard algorithm, and can run directly in the browser. This allows for fast feedback while keying by transforming the tree into LaTeX code. MathJax takes treatment of displaying the in the browser.

When the "Go!" button is clicked, the Integral Calculator sends out the mathematical duty and the setups (variable of integration and also integration bounds) come the server, wherein it is analyzed again. This time, the duty gets transformed right into a kind that have the right to be interpreted by the computer system algebra mechanism Maxima. Maxima takes care of actually computing the integral that the math function. Maxima"s output is changed to LaTeX again and is then presented come the user. The antiderivative is computed utilizing the Risch algorithm, i m sorry is tough to understand for humans. That"s why mirroring the procedures of calculation is very challenging for integrals.

In order to display the steps, the calculator applies the exact same integration approaches that a human would apply. The routine that walk this has been emerged over several years and is composed in Maxima"s very own programming language. It is composed of an ext than 17000 present of code. As soon as the integrand matches a well-known form, it applies fixed rules to fix the integral (e.g. Partial fraction decomposition because that rational functions, trigonometric substitution because that integrands entailing the square root of a quadratic polynomial or integration by components for products of particular functions). Otherwise, that tries various substitutions and also transformations until either the integral is solved, time runs out or over there is nothing left come try. The calculator lacks the mathematical intuition that is an extremely useful for finding an antiderivative, but on the other hand that can try a huge number of possibilities within a short amount that time. The action by action antiderivatives are regularly much much shorter and an ext elegant 보다 those found by Maxima.

The "Checkanswer" attribute has to settle the an overwhelming task of determining whether two mathematical expressions space equivalent. Their difference is computed and also simplified as much as possible using Maxima. For example, this involves writing trigonometric/hyperbolic features in their exponential forms. If it can be shown that the difference simplifies come zero, the task is solved. Otherwise, a probabilistic algorithm is used that evaluates and compares both features at randomly chosen places. In the case of antiderivatives, the whole procedure is repeated with each function"s derivative, due to the fact that antiderivatives are enabled to different by a constant.

The interactive duty graphs room computed in the browser and displayed in ~ a canvas aspect (HTML5). For each role to it is in graphed, the calculator create a JavaScript function, which is climate evaluated in little steps in bespeak to attract the graph. If graphing, singularities (e.g. Poles) space detected and also treated specially. The gesture control is enforced using Hammer.js.
