For You Mathy Mags

I had a dream I forgot to go to my calculus class all semester and tomorrow was the final. I was running around the university campus looking for the classroom. No luck. Crap. Funny thing is, I haven't taken calculus since HS....many, many moons ago. I think I need therapy. ;)
You too may be experiencing thursday-itis, so here are some funnies:

:D

The funny thing is, the first expression here, strictly speaking:

is wrong.

Here's another one:

Close, but the real quote is that the LOVE of money is the root of all evil. I suppose that we could still make it work.

one snowtigerdaniel plus one snowtigress equals 69!!

What do you call a one-sided nudie bar?

A Möbius strip club.

Explain please. I don't think so.

It depends what side of 8 x is approaching from. If x approaches from -inf, the limit is inf. But if x approachs 8 from +inf, the limit approaches -inf.

Plot f(x)=1/(x-8) if you don't see it.

^^
It approaches negative infinity.

Edit:
Damnit. Too slow.

Close, but you got it backwards I think.

Note that if x == 9 > 8, then 1/(9-8) == 1/1 == 1 and if x == 8.1, then 1/(x-8) == 1/(.1) == 10. So as x approaches 8 from the positive side, the limit is inf.

Also note that I don't own anything, anybody and this means absolutely nothing.

The notation used to be :
x->8+ means x approaches 8 from the positive side,
x->8- means x approaches 8 from the negative side.

Yes, I was too fast to show off my mad math skillz. Doh.

Buster, always the enabler of flashbacks

But approaching 8 from a positive value <8 will also approach -inf.

True true.


There should be a "-" by the 5 for the joke to work.


It's still funny as hell.

...but then again, what would a guy who studied Rocks-for-Jocks know? :p
sorry, could resist. had to get you back for outing me as snowtigerdaniel's love interest. :biggrin:

Geology?

I'm a chemist....with a year shy on a masters chem engineering degree.......oh sibling of the shiny feline jacketed one.:fmicon:


My employer has geology folks too but they needed someone smart around so they hired me.:D

There, I fixed it for you. :eek: :D

Seriously, though, a chemist? I thought you did hydrology!?

I do. Sometimes chemicals hang out in water.;)
I do water quality work as well.

There's also the whole I want to live in tahoe so I'll do anything for a real job. Like your guidance teacher told you......math opens doors.:D

I ran this +/- infinity issue by a mathematician friend of mine and he said, well yeah but
"Loosely, though, most mathematicians don't distinguish the two and
just say it goes to infinity."
In other words, DUH.
I think thats my difficulty with math, I could never figure when you had to be precise and when you could just wave your hands and say its obvious.

My calc teachers would have insisted on a +/-

GRRRRRrrrrrrr.............

OK then, too long since I worked with limits.:tdo13:
