Somewhere here, there is a mistake. Can /sci/ find it?

>n/(n+1) = (n+1)
wat

>> No.4678444

>>4678438

yes.

(3) -> (4)

also why (1) -> (2) that way?

>> No.4678447

>>4678438

The first line?

(n+1)436 = 436n + 436
which probably doesn't equal 578n
though if it did, n would be around 0.326

>> No.4678449

>>4678442
n/(n+1)=(n/n)+(n/1)=1+n

>>4678449
DIE

>> No.4678452

>>4678447

whoops, divided the wrong way
n would be around 3.07

>> No.4678453

I know it would have been better to remove the parentheses first. But why is this wrong?

No, no it isn't.

ah, i see what you've done...

>> No.4678461

>>4678449
well, at least you showed how they got that.

too bad that it's wrong. that trick only works with a numerator with multiple terms, not the denominator.

wtf are you doing? they're right, OP is wrong.

>> No.4678477

>>4678470
actually i dont know what the fuck is going on in this thread anymore, anyways the mistake is not inverting the right hand side on line 4 >,>

>> No.4678478

Thank you, I understand the failure.

>> No.4678483

>>4678477
inverting it wouldnt help, then the left side would be wrong.
inverting leaves: (n+1)/n

>> No.4678485

>>4678477
wat. That's not the mistake, the mistake is that you can't split a fracture with a sum in the denominator like that. That only works with a sum in the numerator.

1/n=/=n thats just a minor detail... maybe coming to /sci/ wasnt a good idea after a whole morning of physics, im out
