Well, you hear wrong.

Ugh, trig... I'll never be able to get SOH CAH TOA out of my head for as long as I live. >.<

Ha, I thought this too, but you'd be surprised.

In the modern workplace, at least in the UK, you need to keep your knowledge of maths and English up to date... if your qualifications in the two subjects were acquired longer than five years ago, then you have to do some refresher course rubbish to ensure that you've not forgotten the basics... stuff like spelling, punctuation, grammar, calculating percentages, Pythagoras (cos that totally has real-life application, "oh look, a triangle!"), BODMAS... stuff that I would have thought people never forget and that everyone learns, but in the event that you have forgotten/don't know/suck at their exams, they will shove you into a class to brush up. >.<

I took my GCSEs in 2003 (A* in English Language, B in Maths), and then was told I'd have to take an exam anyway even though I was insistent that there was no need; I'm not usually one for gloating, but getting 100% on both exams was something nice to rub in the faces of the JobCentre's pen-pushers. I would have thought going to university was evidence enough that I at least didn't need to take the English one. ¬_¬

cos(x)^2 + sin(x)^2 = 1 is totally my favourite identity, which one's yours?

I thought that too, so I dropped Maths for AS once I got an A at GCSE. I then found I liked economics and wanted to do it at Uni, so I had to drop German A2 and pick up Maths AS. It's worked well for me, although it wa hard at first.

a^2=b^2+c^2-2bcCosA is fun

Psh subordinate stats isn't that hard

Maybe not hard, but so mind-numbingly dull and time consuming that you wish they were hard. At least they'd be interesting then.

Noooooooooooooooooooooooooooooo!

Memories of my maths teachers nasal whine are flooding back to me...

Trig hmm if only sums would stay that easy take for instance Linear Algebra now there is a boggle.

**Subotan** · 05-17-2010, 13:46

Binomial Expansion anyone?

Uhh just thinking of it brings all the horror back to me the mind wanders I never wish to see any of it again.

The worst is when its an easyish Laplace surprisingly handy but very long far too easy to make a silly mistake in and matrices even handier but even easier to make a silly mistake.

Most the problems follow handy rules but then you end up adding 2+2 and get five cos you were wandering and the whole sums wrong and you cant see where.

Here is a thing I found on the tinterwebby to lighten the mood

The following is an actual question given on a University of Washington engineering mid-term. The answer was so "profound" that the Professor shared it with colleagues, and the sharing obviously hasn't ceased...
Bonus Question: Is Hell exothermic (gives off heat) or Endothermic (absorbs heat)?

Most of the students wrote Proofs of their beliefs using Boyle's Law, (gas cools off when it expands and heats when it is compressed) or some variant. One student, however, wrote the following:

"First, we need to know how the mass of Hell is changing in time. So we need to know the rate that souls are moving into Hell and the rate they are leaving. I think that we can safely assume that once a soul gets to Hell, it will not leave. Therefore, no souls are leaving. As for how many souls are entering Hell, let us look at the different religions that exist in the world today. Some of these religions state that if you are not a member of their religion, you will go to Hell. Since there are more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell. With birth and death rates as they are, we can expect the number of souls in Hell to increase exponentially.

Now, we look at the rate of change of the volume in Hell because Boyle's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand as souls are added. This gives two possibilities:

1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.

2. Of course, if Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over.

So which is it?

If we accept the postulate given to me by Teresa Banyan during my Freshman year, "...that it will be a cold day in Hell before I sleep with you.", and take into account the fact that I still have not succeeded in having sexual relations with her, then, #2 cannot be true, and thus I am sure that Hell is exothermic and will not freeze."

This student received the only A.
