I still need to get sleep. I still need another 20 hours of studying, especially since the prof has a hard-on for systems of linear equations and inverse Laplace transformations involving trig identities..... And the questions involving numerical approximations are probably going to be brutal. It's times like these that remind me how much I am looking forward to getting that Iron Ring.   | ||

I have an exam on numerical methods for ODEs and PDEs this friday.  | ||

Do I know every trig identity he'll end up pulling on us during this exam - hell no..... | ||

 . More than playing sc.Oh, Ordinary differential equations, you crazy americans and your acronyms. That's my favorite subject  . | ||

The only thing I've even really used Laplace/Fourier transform for with DE is to transform PDE to ODE. Explicit numerical approximations are pretty easy to understand (write out the finite difference or whatever order approximation you are using and solve for u), but implicit are more difficult and more time consuming to explain on paper. I've got to agree that the transforms are definitely awesome. Once you realize it could potentially save you a ton of work, it seems easier. Like Stokes' theorem.

Laplace is an awesome way to help solve both ODE's and PDE's. They are usually pretty easy. The rules are about as easy as differentiation rules. Going the other way - it's just as difficult as integration..... But, it is often better than the alternatives. The problem is going to be - this prof loves using trig identities in his tests/exams/assignments. Noticing which ones go where is tricky as hell (he's used identities I haven't seen before, and expected us to know them well). I have spent hours memorizing every trig identity I can find on the internet..... @ flandre - Good luck. I feel your pain. And I am off. More time would have been a blessing..... Maybe I shouldn't have played those 20 games of SC over the weekend..... Or the second half of both the sunday and monday night football games. Too late now. | ||

Btw, I commented in the Ottawa LAN thread about starting up a CSL team, if there was interest. Would you be up for that? | ||

And yeah, CSL could be pretty sweet. I've only got a year and a half left, and I'm still only D- but I'm on my way up! | ||

If you've got 10 hours until exam and you need to study, might as well not sleep. That's what I did for the last 2 exams... regular life cycle does not exist for engineers, period. (I myself a 3rd yr engineer right now) | ||

As for a "regular life cycle", I don't have one either. I've been going to sleep at 7 am, and waking up at 2 pm for the last 2 weeks..... | ||

I wan't very good at it, but I ended up with an A- and only the easy parts of the class still come up for me in third year, so thats pretty alright. And yeah, CSL could be pretty sweet.
