life really sucks sometimes

So I spent from about 3:30 until midnight working on the ECE homework, except for the lab at 6, so I didn't get anything done between about 5:30 and 8:30 because I made food after I came home. So that was like more than five hours, and that doesn't count the hour or so I spent on the first problem before that. And then I only ended up getting a little over half of it done. -.- STUPID COMPLEX NUMBERS!!! Okay, I'm done. But seriously...we're going back to stuff we did at the beginning of the semester. The complex numbers are really the only thing that's different. Simple logic says that's where the problem is. But after a while most of the time I was doing the conversions on my calculator anyway. Maybe I shouldn't have been trusting my calculator, I'm not sure. Because for the first two problems I did all of the conversions by hand, and while the first problem took me a while because I had to figure out the notation and such, I eventually got everything right and knew why it was right. Then, by the third problem, I tried fiddling with my calculator because I knew it could do complex numbers. And from the fourth problem on, everything stopped working. I calculated answers to that one twice, and ended up skipping it because I couldn't get it right, but then ended up calculating answers to the fifth problem three times...and still couldn't get that one right either. I still don't get it...something must have gone horribly wrong with my conversions or something...-.-

The only good thing about today (other than Japanese class ^_^) was that my TAM test was a whole lot easier than I expected. The whole thing was centroids and inertia. I was thinking I was gonna die if they put catenary cables on there, but there were no cables at all! I was quite pleased by that. There was a rather tricky integral though, but I finished like two thirds of the test in the first twenty minutes so I had enough time to patiently work it through with integration by parts. Unless I did something really dumb, the second question seemed kind of odd in terms of points...44 out of 50 points were given for calculating and then adding the results of two integrals, and then the last six were for using another equation, but the result of that equation depended on the result of the previous problem...maybe that was why so few points were assigned to that part, so it wouldn't be so bad if you got the first problem wrong. Well, it'd be bad if you got the first problem wrong in any case, because there are only two problems on these tests. Which was why the previous test was bad, because the second problem was so harshly graded.
