### What is the relationship between a Derivative and an Integral

A derivative and an integral have an inverse relationship. If some function f(x) has an integral g(x), then the derivative of g(x) will be f(x). To be more precise, the integral of f(x) will be g(x) + c, where 'c' is a constant; any constant really. We can't determine it's value from f(x), because when we differentiate 'c', we always get 0, for any value of 'c', provided that 'c' is a… Continue
