Study Notes
Substitution Method in Integrals
- The equivalent of using substitution in integrals is a change of variable, which allows us to transform a complicated integral into a simpler one.
Substitution Method in Definite Integrals
- When using the substitution method in definite integrals, the limits of integration also change: the new limits are found by applying the substitution to the original limits.
Important Step After Substitution
- After making a substitution in an integral, an important step is to rewrite the integral in terms of the new variable, including the differential (dx).
