hmm...

Well, today my calculator is officially dead. That's not very happy, so that's all I'll say about that.

And, I got to troubleshoot one of David's mazes today. I haven't actually finished it. I should try to write a program in C at the end of this semester, which will be able to find the solution to a maze, even with conditions like make only right turns. That would probably be really hard. Maybe not, I don't really know.

Then after work me and David played two games of chess. He won both, but I did better than I thought I would. Especially in the second game, when I actually took his queen. Then made some dumb errors. Oh well, 100 times from now maybe I'll win! :D

equations etc.

Well, in Engineering 207 we were learning about polynomial regression, and how to find the coefficients. that's where you have a bunch of points that basically form a parabola or something.

So Chris Jones (excellent math teacher, I strongly recommend him if you're going to HCC and need math) taught us the really long complicated way. Then he said, "and of course you can use MATLAB to do this for you, it'll be a lot shorter...."

This was at about 3pm.

Back up to 10am: we were taught how to get that line in Excel with 1/10 of the trouble from MATLAB and about 1/1000 of the trouble involved in doing it by hand!!!

I mentioned that to Chris... he laughed and said, oh yeah... now i can make you guys really hate me by showing you this... =) (btw that's just how he talks, idk why.)


I also learned that I can store multi-variable functions on my TI89 calculator. THAT FREAKIN ROCKS!!! :) sorry about that, it was really exciting though.

graphing calculator

Ok... so today in Calculus 2 we learned how to do parametric equations. They're actually really easy and kind of mostly just algebra and then you can do calculus things to them, but it was cool.

But what made me smile was when he gave us an equation, and said "put this in your calculator."
And then it graphed in this funky curve, and it was amusing. i might find a picture later to show you guys.
