Substitution
and definite integration
|
When
we evaluate an indefinite integral of the form
|
|
we
use the substitutions g
(x)
= u and g'(x) dx = du
to obtain
|
|
Therefore,
to evaluate the definite integral using substitution
|
|
or
|
|
Note,
by making substitution the definite integral change the limits of
integration. That is, the new limits of integrations
must correspond to the range of values for u
as we now integrate the simpler integrand f
(u)
from ua
= g (a) to
ub = g
(b).
