Step 1: Identify the limit we want to calculate: lim (x -> 0) (tan(3x)/x).
Step 2: Recognize that this limit can be related to a standard limit form: lim (x -> 0) (tan(kx)/x) = k, where k is a constant.
Step 3: In our case, k is 3 because we have tan(3x).
Step 4: Apply the standard limit result: since k = 3, we find that lim (x -> 0) (tan(3x)/x) = 3.
Step 5: Conclude that the limit is 3.
