Before You Start This Topic

It will help if you are confident with the following:

  • DifferentiationYear 1 differentiation is the immediate prerequisite
  • TrigonometryCompound and Double Angle Formulae}}: needed for many trig differentiation problems
  • Exponentials and Logarithmsneeded for differentiating $e^x$ and $\ln(x)$
  • Functionscomposite and inverse function concepts are essential

A Level Maths further differentiation is the Year 2 calculus topic that extends Differentiation from simple powers of $x$ to a much broader set of functions and techniques. You learn the chain, product, and quotient rules; how to differentiate trigonometric, exponential, and logarithmic functions; and how to handle inverse and implicit functions. Mastery here unlocks Connected Rates of Change, Parametric Equations, Further Integration, and Differential Equations.

You meet the three workhorse rules: the chain rule for composite functions, the product rule for differentiating $uv$, and the quotient rule for differentiating $u/v$. You differentiate trig functions including $\sin$, $\cos$, $\tan$, $\sec$, $\csc$, and $\cot$, and the inverse trig functions $\arcsin$, $\arccos$, $\arctan$. You differentiate $e^x$, $a^x$, $\ln(x)$, and combinations of these with other functions. Implicit differentiation lets you find $\frac{dy}{dx}$ when $y$ is not explicitly written as a function of $x$ — useful for circles, ellipses, and more complex curves. You also differentiate inverse functions using the relationship $\frac{dy}{dx} = \frac{1}{dx/dy}$.

Further differentiation is part of the Pure Maths strand of A Level Maths for AQA, Edexcel, OCR, and OCR MEI students.

Watch out for…

A few things to be careful with: the chain rule is required whenever you differentiate a composite function, so $f'(g(x))$ needs multiplying by $g'(x)$; the product rule is $u \frac{dv}{dx} + v \frac{du}{dx}$, NOT $\frac{du}{dx} \cdot \frac{dv}{dx}$; for implicit differentiation, every time $y$ is differentiated you must multiply by $\frac{dy}{dx}$ (chain rule); and a common slip with trig differentiation is forgetting the chain rule for $\cos(2x)$, which differentiates to $-2\sin(2x)$, not $-\sin(2x)$.
