Dx dx 2) For the first bit, y = 2u2, u = cos x, so I’m having an identity crisis — I can’t differentiate between sin and cos... ). ’ so the examiner can see how clever you are. C3 Section 4 — Differentiation 29 Product Rule In maths-speak, a ‘product’ is what you get when you multiply things together. So the ‘product rule’ is a rule about differentiating things that are multiplied together. And it’s yet another rule you have to learn I’m afraid. ) Examples Differentiate the following with respect to x: a) x3 tan x and a) x3 tan x 1) The crucial thing is to write down everything in steps.
