1. The problem statement, all variables and given/known data This is a limit problem but what I need to figure out is simpler so I thought I'd post it under pre-calc. The question is: Find the limit: lim as x approaches 0 of (tan 2x)/x 2. Relevant equations 3. The attempt at a solution Since x is in the denominator I know that I must re-write (tan 2x)/x so that the denominator doesn't equal zero. I also know that 0 is a root of both the numerator and denominator, but I don't know how to re-write such an equation. Any help? Thanks!
