Question #3 (Medium): Solving Indefinite Integral
Integration by parts is useful when the integral contains two seemingly different function that cannot
further be simplified, so tha∫: ( ) ( ) ( ) ( ) ∫ ( ) ( ) .
This is after the form of the Product Rule. Assign simpler variables like ( ) and let ( ) ,
then by taking derivative of , ( ) and by taking the anti-derivative of , ( ) .
Evaluate the indefinite integral using integration by parts.
The functions cannot be combined or simplified in any other way. So let since it gets simpler
