Derivation: The triangle formed by cube roots of a complex number is equilateral, area formula (\frac3\sqrt34 R^2).

For now, here’s a in the style of MJC 2010 H2 Math Prelim Paper 1: Question (Complex Numbers) Mjc 2010 H2 Math Prelim

So area = (\frac3\sqrt34 (16^2/3)). (16^2/3 = (2^4)^2/3 = 2^8/3 = 4 \cdot 2^2/3 = 4\sqrt[3]4). Derivation: The triangle formed by cube roots of

(c) Find the exact area of the triangle formed by these three roots. area formula (\frac3\sqrt34 R^2). For now

The complex number (z) satisfies the equation [ z^3 = -8\sqrt2 + 8\sqrt2 i. ]

(a) Find the modulus and argument of (z^3), hence find the three roots of the equation in the form (r e^i\theta) where (r>0) and (-\pi < \theta \le \pi).
