Exponential growth, log laws and solving log equations. In Year 13, Calculus, probability distributions and financial maths feature in advanced courses; English demands polished essays under time pressure.
Students will practise: finding the constant k in N = N₀eᵏᵗ from two data points; predicting a quantity at a later time and finding the time to reach a given value; calculating half-life, doubling time and the rate of change dN/dt = kN; converting between the forms N = N₀aᵗ and N = N₀eᵏᵗ.
Clear explanations, examples and tips.
