Quote:Why do you think x=0 [division by] is undefined? Obviously because it would be infinitely big that you couldn't graph it! But go ahead and trust whatever your graphing program saysIt depends on the mathmatical system being used, but division by zero is mostly commonly undefined, not infinite. One of the reasons for this is that if you have x / y = z then z * y = x, in the case of division by zero we have: x / 0 = z, therefore z * 0 = x. Unless x is also zero, any number you put in place of z is incorrect. Therefore division by zero does not yield infinity, or all numbers or whatever, it is undefined. Note that zero divided by itself is also undefined, since we cannot find a single value of z which satisfies z * 0 = 0. Check here and here if you don't believe me.
As far as the physics stuff goes we really need Glen back ;-).
