Jabarkan Integration by substitution dari Integral dalam bahasa sunda

Even if these techniques fail, it may still be possible to evaluate the integral.  The next most common technique is residue calculus.  There are also many less common ways of calculating definite integrals; for instance, Parseval's identity can be used to transform the integral of a square into an infinite sum.  Occasionally an integral can be evaluated by a trick; for an example of this, see Gaussian integral.

Computation of volumes of solids of revolution can usually be done with disk integration or shell integration.

Specific results which have been worked out by various techniques are collected in the list of integrals.
