Question

After choosing \[u=g(x)\], what is the next step?

Options

• Differentiate to get \[du\] and rewrite \[dx\] accordingly.

• Replace \[u\] by the original expression.

• Change \[u\] into a trigonometric function.

• Add the constant of integration.

Answer 1

Differentiate \[u=g(x)\] to obtain \[du\]. Then rewrite \[dx\] so that the differential matches the new variable.
