Question

What is derivative of one function with respect to another in maths?

Answer 1

The derivative of a function of a real variablemeasures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes when time advances.
