i hate trig, part 2

Binomial Expansion anyone?

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.

Philosophy is WAY more sexy than mathematics, I would give it an A too. I've known it to snow in hell...

Well that simply confirms my poor opinion of UW engineering*. Or whoever wrote that. Boyle's law is for situations with constant temperatures (and constant mass). A much more appropriate equation would be the Ideal Gas Law, ( PV = nRT ) which provides for changing temperature and mass.

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

Don't worry; I've forgotten what you're talking about.

well the math test is over.
it wasnt as bad as i thought, i think i may have gotten 2 wrong, but thats part of a 7 question test.
so im not so sure... but he does give half-credit.
but at least its over.

[A Nerd]

7 questions?! They must have been incredibly detailed! It's been a long time since I took math, and never a seven question exam! Good luck to you!

[Hooahguy]

most of our test are 10 questions.

Wow! A lot has changed since I was in school! I remember I took a calculus test during my senior year of high school, I wanted to drop the class at the beginning of the semester after a disasterous couple of weeks of pre-calc my junior year and those arduous few days of my senior year (why I still opted to take calculus I don't know), anyway, I took a test one day and didn't know anything by way of answers for the entire exam, as far as I know I wrote gibberish, but I managed to get a low C. I always thought it was a pity-pass so the teacher didn't look bad. I honestly don't think I subconsiously knew any of the answers. No point or moral to the story, just felt like rambling. I should have majored in English!
