Question

In Method: Resubstitution, what should be done first?

Options

• Evaluate directly using the new limits without resubstitution.

• Consider the integral temporarily without limits and make a suitable substitution \[t=g(x)\].

• Change the lower limit to \[t_{lower}=g(a)\] before finding an antiderivative.

• Add +C to the definite integral.

Answer 1

Resubstitution begins by considering the integral temporarily without limits. A suitable substitution such as \[t=g(x)\] is then made.
