Best ResponseYou've already chosen the best response.0Tan y/x. Book says 1, isnt it real/imag? How did they get that?

Best ResponseYou've already chosen the best response.0I know they got the mag. by mult. by conjugate.

Best ResponseYou've already chosen the best response.0Hum. Ok. The book just says use y/x (pchem book). If z=x+iy, and the mag is sqrt 2, can you not just say y/x?

Best ResponseYou've already chosen the best response.1Yes, but I thought you were having trouble with it conceptually :P so i went into a little more detail lol

Best ResponseYou've already chosen the best response.0Thanks for that! I actually understand the graph! Been doing Pchem all day and brain fried.

Best ResponseYou've already chosen the best response.1Therefore: \(\large\rm arctan\left(\frac{y}{x}\right)=\theta\)

Best ResponseYou've already chosen the best response.1Ya I guess we gotta be careful with our y, right? We're thinking of our complex number \(\large\rm z=x+iy\) So the i is not included in the y. It's just the distance in that direction. So ya y=1, good good

Best ResponseYou've already chosen the best response.0arctan (1/1) does not give 45 degrees though.

Best ResponseYou've already chosen the best response.1no? :o it should. are you in radians, maybe it's spitting out pi/4 as a decimal value
