This is like Charlie Brown's teacher talking to me.
Oh, I know. Where the hell are we supposed to learn about complex numbers, anyway? It wasn't in the Trig for Dummies book I read. Is it a precalculus thing? Because those are the two (general track) math courses I didn't take, and I keep running into "Of course, we all remember how to do the blah blah..."
Yeah, I thought it wasn't bad fluff. And I've always liked Dean from Gilmore Girls. Who is not Dean on this show.
No! This is about polar forms, or how to express 3-4i as |z|(cos theta + i sin theta). I'm okay with the z (it's 5), but I'm a little unsure about theta. From my notes, apparently it's inverse tangent(-4/3), but then I should check to make sure the angle measurement I come up with is in the right quadrant, and that's where I get a little uncertain.
All true, and the quadrant you wind up in will be the lower right quadrant. The real part of your number (i.e. the 3) appears on your x axis, so you'll be right rather than left. The imaginary part (the -4, i.e. the coefficient of i) appears on the y axis, so you're lower rather than upper.

And what did you think constitutes my target audience?
Thanks, Sean!

See, that's so not me. I barely scraped through high school math and never even took calculus, and in college I managed to take some History of Math course with an insane old guy who wore a beret and made us read Flatland and the annotated Alice in Wonderland. And I still use my fingers when doing basic sums half the time. I applaud all you mathy types because your brains are so sexy. I have a mad crush on Charlie from Numb3rs.

That made me blink a few times, too.

It's true, my sex organ weighs 8 pounds and you can't fit your hand around it.

Of course! Of course you are! What the fuck is wrong with me? No, I'm serious. For some reason I was putting it upper left, which is entirely the freaking opposite of what I want!

Yes, but it's all floppy and wiggly and where's the fun in that?
