Abdullah A.
Answer:

Function derivatives can be thought of as the rate of change of the original function with respect to its variable(s). Most of the physical and chemical phenomena around us could be described as functions that depend on one or more variables. Therefore, by deriving these functions we could understand how these phenomena would be affected by their variables.
