### Re: lim

Is n a real constant? Or a natural number?
Also, how did you get 6x George?

sinx/n

Cancle out the n's...

And yes, that is the answer your teacher is looking for.

"In the real world, this would be a problem.  But in mathematics, we can just define a place where this problem doesn't exist.  So we'll go ahead and do that now..."

### Re: lim

sin and lim , not lin

lim means limit.. for example a number that some sequence is approaching.

What does this approach?
0.9, 0.99, 0.9999, 0.9999999, 0.99999999999, 0.999999999999999999, 0.9999999999999999999 ...

### Re: lim

Then don't post here.

Sin = Sine

As for lim, it means limit.

Sin = o/h

The rule is that:

(a/sinA) = (b/sinB) = (c/sinC)

Very easy to remember.

### Re: lim

Not 'sim', 'sin'.

Just imagine how silly 'sime' would sound.

'lim' is used in equations when trying to express...well, just read polylog's post, I can't be bothered to explain something someone already has.

'sin', like I said before, is used for calculating a side (or an angle, they'll teach you about that later when they get into cos and tan, etc.). Say, I need to find x, I would use the sin rule to find x.
