hahaha! Got these in my email today. Not sure where they're from but they're funny!

those are friggen HI-LARIOUS!

Those are great! My fave has to be the limit one, with the "expand" coming a close second. PS - on the Limit ones, shouldn't the answers be negative infinity?Or does LIM x->5 inherently imply x approaches 5 from > 5? I'm getting rusty in my old age

I'm getting rusty in my old age oh man, i flunked out of calculus so i think i would have answered #3 the same way . i think i quit going to class after 3 weeks in to it. i was failing it anyway and the prof wasn't any help. i like the "expand" one too.

I'm so bad at math I don't even get it... haha six=6...

my favorite is the "here it is" in otherwords stop making me do stupid math equations.

I'm getting rusty in my old age Doesn't it include the approaches from both greater and less than 5? Anyway, those are good (although the first one took me a second).

hahha these are good.the limit of x -> inf. should be from both sides, and since 1/x-8 can go to infi. its a positive inf.

wow those are great!!!

It's a hyperbole....So the answer is +/- infinity. However, ifyou want to get technical, infinity is a conceptual limit that has no sign value, so negative infinity is non-existent. We only use negative infinity for some of us to understand that it grows to the left of the zero...Better yet, some mathematicians theorize the number line isn't a line...rather like the earth it is round...which further supports the definition of infinity......hopefully that didn't kill the thread, although I'm sure it killed off any cool points I may have previously attained on this forum.

now see you just lost me i feel like a duck in the ocean..help i'm floundering in mathematical concept.
