Function: ldefint (<expr>, <x>, <a>, <b>) Attempts to compute the definite integral of <expr> by using
limit to evaluate the indefinite integral of <expr> with respect to <x> at the upper limit <b> and at the lower limit <a>. If it fails to compute the definite integral,
ldefint returns an expression containing limits as noun forms.
ldefint is not called from
integrate, so executing
ldefint (<expr>, <x>, <a>, <b>) may yield a different result than
integrate (<expr>, <x>, <a>, <b>).
ldefint always uses the same method to evaluate the definite integral, while
integrate may employ various heuristics and may recognize some special cases.
There are also some inexact matches for
?? ldefint to see them.
