Best ResponseYou've already chosen the best response.0Here is whtat the book says do but I dont get it. 6i=r cos theta + i r sin theta r=6 (why?) inverse tan (6/0) is pi/2 so it is 6e^(I PI/2)

Best ResponseYou've already chosen the best response.1the "r" factors out r ( cos x + i sin x) the magnitude squared is r^2 * 1 (right?) and square root gives r
