I hate senior year classes. Everything is impossible. For the Control homework I started today the second problem has to do with Laplace transforms, which for the very large portion of the world lucky enough never to have to deal with them, is kind of a tricky way some French guy came up with to avoid calculus. Nowadays we have computer programs to do this for us, but nevertheless, we're made to learn it.
So I get to the first part of the problem and after two pages of algebra, still can't do it. So I put it into the symbolic math program I have, Maple, and get this answer:
y(t) = -1/60*2^(1/3)*3^(1/2)*(2^(1/3)+2)*exp(1/2*2^(2/3)*t)*
sin(1/2*3^(1/2)*2^(2/3)*t)+(1/60*2^(2/3)
-2/15-1/30*2^(1/3))*exp(1/2*2^(2/3)*t)*
cos(1/2*3^(1/2)*2^(2/3)*t)+(1/30*2^(1/3)-1/15
-1/60*2^(2/3))*exp(-2^(2/3)*t)
+1/5*exp(t)
And I was supposed to get *that* answer?!
Holy freaking crap.
