Sounds like some people don't go camping enough !!!! ;D
knowing some of this is partly how i pay for my camping... :)
All seems pretty straight forward
Who would have thought I went through so many years and never heard of factorials.
I've only come across them when doing statistics. I hate statistics, so I don't use them often :)
Where I really drew the line was with laplace transforms (http://en.wikipedia.org/wiki/Laplace_transform) hated that stuff with a passion.

I didn't enjoy calculus at all....wasn't any more enjoyable when the kids did it, either.... :(
I loved matrices, and the imaginary number i, which allows the square root of negative numbers to be calculated....
Ha, even though I had very little exposure, hexadecimal was another form of calculation that I never got my head around fully ..
Is your calculator in degrees or radians? Should be in your options menu.
Calculus is good if you have a good teacher, when I first learnt it in high school I really struggled, but in Yr 12 I got a better teacher and really got to like it. The basic concept is rather simple, the way it is written (with all the different notations) is what makes it confusing.
I always entered 5318008 and turned it upside down
Sent from my fingers via my brain
Only the eggheads in advanced maths knew THAT formula.With the old calculator 0.7734 used to work, because the 4 was displayed differently

You maths gurus might be able to help me ;D
With regards to psi and in hg, is one a linear form of the other, but in an opposite form of pressure? (That doesn't make much sense does it ??? )
Say if I had a mechanical force of 10 psi, applied to a valve, then added a 10 in hg vacuum to the same side of the valve, will this equal out zero?
Does that make sense?

By hg, I assume you mean mm of mercury (Hg). If so then 10 mm of mercury is about 0.193 PSI, so no they would not cancel out and the valve would stay shut. If you wanted the direct opposite for PSI it would be Torr, so 10 PSI applied to one side of the valve and 517.1 Torr pulling it down, would equal out to zero.
That ^ is slightly at odds with your sig line Symon...... ;D ;D ;D
The calculation for the numbe 5 is specified incorrectly. The exclamation mark is placed underneath the square root symbol, so it actually readsSQRT(9x8x7x6x5x4x3x2x1) = 602 (approx)
And not the intended(SQRT(9))! = 3x2x1 = 6

An inch of mercury is ~ .491 psi, you would need just over 20" of mercury to balance the 10 psi
