We're having an exam on math soon, so I'm looking for some source on which I can find math theory proofs, do you guys know any?

#2

I got about tree fiddy of them.

#3

Can you be a little more specific?

#4

#5

Smoke pot

#6

Wikipedia has something.

#7

#8

Predicate logic proofs are way more fun than math proofs.

#9

Predicate logic proofs are way more fun than math proofs.

Except that it counts as an error of judgement during exams.

#10

I need to prove every theory related to differentials

Ok. Someone tell me where that goes wrong!

#12

the 4th line where the dividing happens is shady. denominator man, come on.

Tell me which proofs please.

#14

Tell me which proofs please.

If the function can be differentialed(don't know the english term) in a certain point, then the function is not um... doesn't have a gap there, if that makes any sense, I can study scientific english only from next year :|

^ for starters.

#15

Sorry, I don't follow... what do you mean by doesn't have a gap there?

#16

Well, it means the function exists, for example in 1/x, the function in x=0 doesn't exist

****ing awesome.

So you want to prove that if you can differentiate a function, the function =/= 0 ?

#18

No, the theory that states that if you can differentiate a function in a certain dot, than the function exists in that dot and can be found

#19

Perhaps he means that if a function can be differentiated at a point, then it is continuous at that point.

#20

Dividing by 0 will do that.

This is wrong, dividing doesn't work that way.

#22

It does, it's perfectly right.

Except for the fact that A-B=0, but generally it's a paradox

#23

Yep, it's right. Took a closer look at it.

EDIT: Oh, yeah, there's that dividing by 0

Do the equation where A=B=1 and you will see where it falls apart

#25

Just do what everyone does, try and do as much of the proof as you can, then just write what you're trying to prove it equals.

What?

And logic is much cooler than maths.

I know.

I asked 'what?', as in, what do you mean?

Well considering math is composed completely of logic, I'm not seeing the difference
