1. The problem statement, all variables and given/known data Evaluate the square 0f 5e^(3(pi)i)/4 without using Cartesian form, and also the three different products. 2. Relevant equations e^i(theta) = cos(theta) + isin(theta)? 3. The attempt at a solution I have absolutely no idea here, nothing in my notes even begins to suggest how I can answer this.
