1. 40. Grade A Questions Complex Numbers [2021]

We covered Complex Numbers Grade-A questions, focusing largely on Polar (Modulus/Argument) forms. These included plenty of trigo manipulations - do note all the supplementary, complementary and negative angle properties. Also, be mindful of half-angles. As mentioned, we can manage this in two ways - via trigonometric manipulation, or the half angle factorisation trick. Regardless of approach, do get familiar with these, it's modern A-levels trend :)
