Differentiation (which, like integration, is part of calculus) is the process we use to find gradients. Recall that during GCSE Maths, we saw how to find the gradient of a straight line. At A-Level Maths, we learn how to find the gradient of a curve. Differentiation from first principles is based on finding the gradient of the straight line obtained when zooming in at a point on a curve.
