2 Example If f(x) = ex + 2ex, find f’(x) for x = 0. 1) Let’s break down the function into its two bits and differentiate them separately: 2 y = ex and 2) This is the tricky bit. Use the chain rule from the last page: u = x2 and y = eu y = 2ex 5) This bit’s easy. If y = 2ex then dy = 2ex too. dx 3) Both u and y are now easy to differentiate: du = 2x and dy = eu du dx 2 dy du dy 4) = × = 2x ∙ eu = 2x ∙ ex dx dx du When y = kf(x) where k is a constant, then dy/dx is just kf ’(x). 6) Put the bits back together and you end up with f’(x) = 2xex + 2ex.
Dx 2) To find dv for the product rule, we need the chain rule twice: dx v = u12, where u1 = tan (3x). dv = 2u = 2 tan (3x), and du1 = 3 sec2 (3x) (which is an easy chain rule solution itself). So dv = 6 tan (3x) sec2 (3x). 1 dx du1 dx dy 3) Now we can put this result in the product rule formula to get : dx dy = (ex ∙ 6 tan (3x) sec2 (3x)) + (tan2 (3x) ∙ ex) = ex tan (3x)[6 sec2 (3x) + tan (3x)]. Job done. dx du dv dx dx u v Differentiate Again for d2y/dx2, Turning Points, Stationary Points etc.
C) After how many years will the motorbike’s value have fallen below £500? d) Sketch a graph showing how the value of the motorbike varies with age, labelling all key points. Feeling confident? Thought so. Let’s see how you handle these exam-style problems — they’re a wee bit more problematic... Exam Questions 1 a) Given that 6ex = 3, find the exact value of x. b) Find the exact solutions to the equation: e2x − 8ex + 7 = 0. c) d) Solve the equation: giving your answers as exact values of x. 2 The sketch below shows the function y = eax + b, where a and b are constants.
