Maths Problem

[AngelicVampire]

Seems about my level right now!

[Sleepyjack]

Ha, i quite like that one

[Siege]

At first I was confused. Then I was laughing, both at the joke, and at me

[Willravel]

Oh man that's good...hahahaha!

[rsl12]

That's very cute!

[rlbond86]

lmao!!!!!!

[KellyC]

K....so that's two threads that makes me laugh out loud. Thanks!

[liquidlight]

Apparently I'm the only one not getting this. . . :P blame it on sleep deprivation and the fact that I haven't had a math class in 8 years hehe

Try looking at the last answer again.

Then look at it again.

You'll see.

It's a good one!

Edit: you won't need expert math knowledge. The student apparently didn't

[Redlemon]

Nice nice nice. I dropped this in a Blonde joke thread, but I'll drop it here as well, since it is more appropriate here.

[Mantus]

I like that, thanks!

[Zeraph]

LOL at both, good ones.

Here's a hint for those that didn't get it, on the second one the answer is a sideways 5, which isn't a real symbol like the sideways 8 meaning infinity. Now take another look at them and why the student doesn't get it (IIRC they both equal infinity).

[Nimetic]

That's cool. Sheesh. It reminds me that mentoring/teaching sure has it's moments.

[Nimetic]

Loud laughter. Oh shit. That's great.

[gamefreak1398]

although the first answer's wrong also XD
but good joke lol made me chuckle

[AngelicVampire]

Why is it wrong? As X tends to 8 the sum becomes undefined (1/0), however as it approaches it for values say 7.9999 the value becomes very large (1/0.0001 = 10,000), so it does approach infinity. Of course a sideways 5 is wrong though...

[Daniel_]

Funny.

Fuuuuuuuuh-neeee!

[Randomfunk]

Have to admit I sat here for a good minute or so trying to work out what the symbol was in the second one before I actually realised what it was...

[Gilda]

Chalk me up as another who didn't understand the joke until it was explained. The first one made no sense to me, so it really wasn't possible for me to process the second in any way.

it's wrong because it approaches both infinity and negative infinity
so the limit actually does not exist.....

unless the limit says x -> 8+ then it would be infinity
but it doesnt have the + after 8, so it approaches 8 from both sides
yes, from the right, the limit does approach infinity
but when it comes from the left, it approaches negative infinity

you can make it right by squaring the denominator of the equation, then the limit would approach infinity

so that's why it's wrong
but good joke

love it. isn't math wonderful?

A more asthetically pleasing fix would be to just make the whole thing the absolute value.

[SirLance]

Oh, god, I'm gonna wet my pants...

[dun_ask]

haha good joke, I didn't get it at first until I really looked at it. Hizzah!
