should we learn the geometrical derivations for Physics?

Derivations will help you to understand any formula is derived. In case, you forget any formula understanding the derivation will help you to arrive at that formula. Instead of byhearting understand the derivation with the help of its corresponding diagram. This will help you to remember it in a much better way. By knowing derivations it will help you to answer any type of numerical related to that derivation. So, it is always beneficial to learn and understand derivations.
