Support · Mathematics Extension 2 11–12 – Year 12 · Introduction to complex numbers

Support Define and calculate the argument of a non-zero complex number z = a + ib as arg⁡(z) = θ, where θ satisfies sin⁡θ = b/(z) and cos⁡θ = a/(z), noting that the argument has multiple values that differ by multiples of 2π

Prerequisite dot points

Use the product rule to prove that if P(x) has a zero, α, of multiplicity m > 1, then α is a zero of P'(x) of multiplicity m - 1, and use the result to determine the multiplicity of a discovered zero of P(x) and solve related polynomial problems

Define α as a repeated zero or multiple zero of a non-zero polynomial P(x) = (x - α)Q(x) when (x - α) is a factor of Q(x), and α as a single zero of P(x) when (x - α) is not a factor of Q(x), for Q(x)≠0

Examine the graphs of the composite functions (y = sin)^(- 1)⁡(sin⁡x), (y = cos)^(- 1)⁡(cos⁡x) and (y = tan)^(- 1)⁡(tan⁡x), establish the values of x for which the formulas sin^(- 1)⁡(sin⁡x) = x, cos^(- 1)⁡(cos⁡x) = x and tan^(- 1)⁡(tan⁡x) = x are true, and apply the formulas to solve problems, simplify expressions and prove results
