Complex division: (a + bi) / (c + di) = [(a + bi)(c - di)] / (c^2 + d^2)
Polar to Rectangular: z = r(cos θ + i sin θ)
Rectangular to Polar: r = √(x^2 + y^2), θ = arctan(y/x)
Multiplication in Polar Form: r1 * r2 [cos(θ1 + θ2) + i sin(θ1 + θ2)]
Division in Polar Form: r1 / r2 [cos(θ1 - θ2) + i sin(θ1 - θ2)]
Theorems
