1. The problem statement, all variables and given/known data Add the formulas y1 = 5.2 sin(ωt), y2 = 8.3 sin(ωt+30°), y3 = 15.5 sin(ωt+60°) using the phasor method. Your formula should only have numbers and the variables ω and t. The formula must be accurate for any value of those variables 2. Relevant equations Not sure. 3. The attempt at a solution Know I need to do algebra, but not sure how.
