Feedback and error review.

Try this with Mathematics Methods

1. Choose one criterion, teacher comment or mark you want to understand.
2. Compare your answer against that criterion and rewrite only the part that missed it.
3. Try the same skill on a fresh task to see whether you can apply the feedback.

• Euler's number e, the limit (a^h - 1)/h and the derivative of e^x and Ae^(kx)
• Derivatives of sin x and cos x and their use in practical problems
• The product, quotient and chain rules and composite functions
• Second derivatives, concavity, inflection, the increments formula, curve sketching and optimisation
• Indefinite integrals of x^n, e^x, sin x, cos x and f(ax - b), linearity and initial conditions
• Area as a limit of sums, signed areas, additivity and linearity of definite integrals
