Maxima 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.
