What must be done before integrating after obtaining \[du\]?

पर्याय

• Express the entire integral in terms of the new variable.

• Keep the integrand in terms of both variables.

• Express only \[dx\] in terms of the new variable.

• Add \[C\] before rewriting the integral.

Answer 1

The entire integral must be expressed in terms of the new variable. This includes both the function and the differential.
