Yesterday I stayed home because I was sick. It sucked. And then I read the response e-mails from my teachers. And it turns out it sucked worse than I had originally thought. Apparently, there's a project that my Calc III class is doing, and I missed the initial discussion day for it. For anyone who doesn't know how things like this go (Not that I expect there are that many,) if you miss the first day of a project (Which I think might be a group project... *eeep*,) you are destined to have only half of the time and absolutely no idea what's going on. *Sigh*

I also have a project due frighteningly soon in my Diff EQ / linear Algebra class. I've chosen a very easy project to do, an Euler model (Pronounced Oiler... Stupid French language) of an already separated differential equation. Thus I write a program that looks something like this:

Declare a function f that accepts the parameter t and returns the change in value at t.

Declare a constant called dT and set it equal to the time step.
Declare a constant called TMin and set it equal to the start time.
Declare a constant called TMax and set it equal to the end time.
Declare a variable t.
Declare a variable y and set it equal to the initial value.

Starting with t equal to TMIN and looping till t is greater than TMax, increasing it's value by dT every loop: add the result of the multiplication of the function f at t against dT to the value of y then display t and the new y.

Where the function F is provided to me by the teacher and TMin, TMax, and the initial value for y are provided by the teacher. Should be easy, but he wants it to make some graphs too. I may just push the output into Excel and have it do it... We'll see.

I need a vacation.
