Differentiating Combinations for AS & A-Level Maths
Once you’ve mastered the building blocks of differentiation for A-level maths, the next step is to get comfortable with the various rules – what happens when you have a function with something complicated inside the brackets? How about if you have expressions involving addition, subtraction, multiplication or division? This table reminds you what to do in these situations, including the dreaded chain rule, quotient rule and product rule from Core 3.
If you’re doing parametric differentiation in Core 4, then dy/dx = (dy/dt)/(dx/dt).
