Defint

Function: defint (<expr>, <x>, <a>, <b>) Attempts to compute a definite integral. defint is called by integrate when limits of integration are specified, i.e., when integrate is called as integrate (<expr>, <x>, <a>, <b>). Thus from the users point of view, it is sufficient to call integrate.

defint(x,x,a-b,a);
eq1:sin(w*x);
eq2:defint(eq1,x,a-b,a);
laplace(eq2,a,s);

defint returns a symbolic expression, either the computed integral or the noun form of the integral. See quad_qag and related functions for numerical approximation of definite integrals.

There are also some inexact matches for defint. Try ?? defint to see them.
