Homework Help: Limit as x goes to 0 of ((sin(x)/x) - 1) /x

1. The problem statement, all variables and given/known data
Find the value of the limit as x goes to 0 of ((sin(x)/x) - 1) /x WITHOUT L'HOPITAL'S RULE.


2. Relevant equations



3. The attempt at a solution
I tried to get the expression inside the limit in terms of the fundamental trig limits, but all I got to was (1/x)*((sin(x)/x) -1). I want to say that the limit of this product as x -> 0 is equal to the desired derivative, and that since the limit of the ((sin(x)/x) -1) part as x -> 0 is 0, that the value of the limit is 0.

However, I'm not convinced that this solution follows from the basic limit laws. In fact, I don't think it does, since lim(1/x) as x-> 0 does not exist. How can I solve this question without using L'Hopital's Rule?
