This video talks about the change of variables and substitution to make an equation solvable. Also, scaling is discussed in various differential equations to change units, make unit dimensionless, or to reduce the number of or simplify constants in a function. Some examples are shown, and this video covers a lot of very important and intense differential equations topics.
