These videos explains how to:
1. Understand the gradient of a curve at a point as the limit of the gradients of a suitable
sequence of chords, and use the notations f′(x), f ″(x), dy/dx and d2y/dx2 for first
and second derivatives.
2. Use the derivative of xn (for any rational n), together with constant multiples, sums and
differences of functions, and of composite functions using the chain rule.
3. Apply differentiation to gradients, tangents and normals, increasing and decreasing
functions and rates of change.
4. Locate stationary points and determine their nature, and use information abou
