Pretty much this. You look at the numbers as they get closer and closer to 0 and see where it converges and assume that must be what the number actually is at that point. This is one of the basic ideas behind derivatives. |
Its not division by zero, its division close to zero. There is a fundamental difference between dividing between an infinitely small number and division by zero. Thats the reason why you always have to express it with limit notation (lim x-> 0 of 1/x is infinity) rather than 1/x is infinity.
