Overview

Form 5.

Learning objectives

What the syllabus expects you to be able to do.

  1. 6.5.1.1Form 5: differentiate from first principles (polynomials, rational and trigonometrical functions; not logarithmic or exponential functions).
  2. 6.5.1.2Form 5: differentiate polynomials, rational functions, natural logarithms, exponentials and trigonometrical functions.
  3. 6.5.1.3Form 5: differentiate sums, differences, products, quotients and composite functions.
  4. 6.5.1.4Form 5: carry out implicit and parametric differentiation.
  5. 6.5.1.5Form 5: find gradients, tangents, normals and rates of change.
  6. 6.5.1.6Form 5: locate stationary points and distinguish between maxima, minima and points of inflexion, and solve problems involving differentiation.

Differentiation: sample question

1 mark

The tangent to the curve y=x2−5x+3y = x^{2} - 5x + 3 at the point where x=4x = 4 meets the yy-axis at (0,c)(0, c). Find cc.

Complete: c = …

Only if the answer has a unit, e.g. cm or km/h.
