I am *not* having a good day.

Firstly, my period is due today, which gives you some idea of my approximate mental state, i.e. 'terminally screwed up and completely unstable'.

Secondly, when I arrived this morning I was told that I have to do a Cambridge personal statement after all, despite Mrs Ingle telling me that my best shot was worthless and that it was better to put nothing than to put something worthless and that it was my choice.

Thirdly, during being told this I burst into tears. I still feel like crying, I keep having to blink a lot. This didn't help anything, and made me feel most embarrassed too.

Fourthly, we're now doing more stuff about trigonometric calculus in maths, which is the one thing I absolutely cannot understand. Even graphs of rational fuctions aren't quite as bad. And I'm certainly not in the correct mood to take any of it in, hence not even trying; it'll just make me cry more.

Hold it ... rational functions? As in functions from Q to Q (Imagine they had vertical bars in okay?)?

Why would you be studying functions from Q to Q?

Uhm... it's just graphs of functions which just have powers of x in... (i.e. working out the graph from the equation, or vice versa)

Functions composed of the ratio of two polynomials?

What a stupid name for them. Ho hum.

Hmm, some of those could get quite annoying to draw (I don't actually have much of an idea what x+x^2/3 (hold on ... you couldn't get that from the ratio of polynomials. Hmmm.) looks like, for example. Well, okay, take a derivative and work from there I guess.)

(And working out the equation from the graph ... yuck. I'm glad we never had to do that in maths.)

Yes. It is truly evil, and I can't do it. (Which would be fine, if I could do the trig integration and imaginary-numbers-in-polar-form stuff also in this module, but I have fun with those too.)
