Question

What is a standard integral?

Options

• An integral containing only the numerator \[px+q\].

• An integral that has no constant of integration.

• An integral whose result is already known and can be directly used after suitable algebraic simplification or substitution.

• An integral that always requires partial fractions.

Answer 1

A standard integral has a known result that can be applied directly. Complicated expressions are simplified or transformed by substitution into a known standard form before integrating.
