"Derivative" action is used to set up the derivative notation quickly and efficiently. 

"Compute" action on the other hand is used to compute derivatives as a sub-problem. 

Let's see these two actions on an example to have a better understanding of how these actions can be help us create solutions more effectively in Gradarius. 

Compute action is very useful when you have multiple derivatives in a problem and you want to take care of them one at a time as a subproblem.
