Differentiation (International Specifications)

By the end you’ll be able to

• Differentiate $ax^n$ for integer $n$ and sums of such terms, e.g. $y = 2x^3 - \frac{4}{x}$
• Find the gradient of a curve at a point and the equation of the tangent at that point
• Find turning points by solving $\frac{dy}{dx} = 0$ and decide whether each is a maximum or a minimum
