This will be calculated:
Not what you mean? Use parentheses! Set integration variable and bounds in "Options".
Above, enter the function to integrate. Variable of integration, integration bounds and more can be changed in "Options". Click "Go!" to start the integral/antiderivative calculation. The result will be shown further below.
How the Integral Calculator Works
For those with a technical background, the following section explains how the Integral Calculator works.
First, a parser analyzes the mathematical formula. It transforms it into a form that is better understandable by a computer, namely a tree (see figure below). In doing this, the Integral Calculator has to respect the order of operations. A specialty in mathematical formulas is that the multiplication sign can be left out sometimes, for example we write "5x" instead of "5*x". The Integral Calculator has to detect these cases and insert the multiplication sign.
Maxima takes care of actually computing the integral of the mathematical formula. Maxima's output is transformed to LaTeX again and is then presented to the user. The antiderivative is computed using the Risch algorithm, which is hard to understand for humans. That's why showing the steps of calculation is very challenging for integrals.
