No, no, the axes are... not quite arbitrary, but it feels that way when learning which way around they go.
I didn't actually transpose them. What I did was, I took 4/-3 and made it -4/3, which is entirely okay, and then I forgot that it was originally the 3 that was negative when deciding the quadrant. (ETA: Actually, it was the 4 that was negative in the first place, so I have no excuse at all -- I forgot which was x, I suppose.)
So, then, if the inverse tangent of 4/3 is 53.13, and I want it to be in the fourth quadrant (because it was the duck, and not the man, that spoke), I do 360-53.13, which gives me 306.87, and thus the cosine is positive and the sine negative (important, because the reverse was true when I did 180-53.13). Yes?
I know it's a cliche by now (or "clich" as they say in fanfiction archives), but thank goodness for chef billytea.
My brain is a festering stew of popculture references.
ETA: If anyone's following the saga, this means I got 3-4i = 5(0.6-0.8i) or 5e^(306.87i).
ETA2: Oh. My. God. Am I really that much of an idiot, that 3-4i = 5(-0.6+0.8i) didn't seem a little odd just on the face of it? Yes. Yes, I am. ARGH!
I shall be quite disappointed if ita's African trip doesn't include running down and killing a cheetah barehanded. I mean, they're lying around on the ground in the open there, it's the perfect opportunity.
(Hmmm, you wouldn't know that I just recently came home from a rigourous yet spiritual yoga class, would you?)
Am I really that much of an idiot, that it didn't ring any bells earlier that 3-4i = 5(-0.6+0.8i) didn't seem a little odd just on the face of it? Yes. Yes, I am. ARGH!
Math geeks are hot. Even I don't understand a word they say.
It's just that 5*0.6=3 and 5*0.8 = 4, so I'd basically written 3-4i = -3+4i and it hadn't occurred to me. Mind you, the idea that I'd gone through that whole find-the-theta-by-inverse-tangent thing when all I had to do was divide by 5 makes me kind of irked. But I suppose he probably wants the e^i theta form as well, so I guess it was worth it.
I suppose the bit where the endpoints are equal to each other arithmetically serves as a good check, huh? I just... didn't realize. I guess I still think of trigonometry as this sort of arcane "other" thing and don't think about it coming back around to give me the normal numerical values. Thank you!
OMG Emily, I can't believe you didn't get that immediately.
...um, just kidding.
So I heard the other day that Jon Stewart is apparently by my school all the time, likely bringing his dog to the doggy day care place next door to the building with the computer lab I never go to. I'm thinking I should re-jigger my routine.
So, I just finished watching episodes 4x01 and 4x02 of Spooks and GAH. This show rocks my world. Also, more Buffistas should be watching it because it's hella smart, stylish, with compelling characters and moral ambiguity up the wazoo.
Also, the lead agent is ungodly hot and there was shirtlessness in the first episode. What more do you need?
Right.
