Best ResponseYou've already chosen the best response.1Eyyy :) So what are we having trouble with? The modulus is just the length directly to that point, ya? So like,dw:1433125698294:dw

Best ResponseYou've already chosen the best response.1Mmm sorry sloppy hand writing _ that's a \(\Large\rm z\) on the graph

Best ResponseYou've already chosen the best response.1Or if you're more comfortable looking at it in polar form, you can do the steps to convert it into \(\Large\rm z=r e^{i\theta}\) Where our modulus is r, and argument is the angle theta, err principle argument at least. Mmmmm what are you thinking ms Hailey? :d

Best ResponseYou've already chosen the best response.0I got sqrt 2 for my modulus and pi/4 for my argument

Best ResponseYou've already chosen the best response.1yayyyy good job \c:/ do they just want pi/2 for the arg z? Or do they want the rotations and stuff also? so maybe pi/2 + 2k pi. I dunno i can't remember >.<

Best ResponseYou've already chosen the best response.1The `principle` argument, yes, is \(\Large\rm \frac{\pi}{4}\). But notice that \(\Large\rm \frac{5\pi}{4}\) is also an acceptable angle, I just spun a full time around the circle and landed in the same spot. If you haven't talked about that in your class, maybe we shouldn't worry about it :)
