⭐ Magdy Math Golden Rule
Find the inside function $u$. Make sure its derivative $du$ is sitting right next to it!
Common Sub Choices
Powers: $u = \text{base of the power}$
Roots: $u = \text{expression under root}$
Trig: $u = \text{angle}$
Exp: $u = \text{exponent}$
Log: $u = \ln x$ is a great choice if $1/x$ is present.
