Enter the function you want to integrate into the editor. The Integral Calculator solves an indefinite integral of a function. You can also get a better visual and understanding of the function and area under the curve using our graphing tool. Integration by parts formula: ?udv = uv−?vdu? u d v = u v -? v d u.

Enter the function you want to integrate into the Integral Calculator. Skip the f (x)= part and the differential dx! The Integral Calculator will show you a graphical version of your input while you type. Make sure that it shows exactly what you want. Use parentheses, if necessary, e.g. a/ (b+c).
You could Parseval's theorem $$\int \!dx \,f(x) g(x)^* = \int \!d\xi\,\hat f(\xi) \hat g(\xi)^* $$ with $f(x) = \sin(x)/x$, $g(x) = \Theta(x) e^{-x}$ and $\hat{f}$, $\hat{g}$ their Fourier transforms and $\Theta(x)$ the Heaviside step function.
∫ e^x sin x dx: This is a lovely example of integration by parts where the term you are trying to integrate will keep repeating and you end up going in circles. This example is to show how to solve such a problem. As usual you choose the simplest term for u hence u=e x, and therefore du/dx=e x.
