Homework Statement
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
Homework Equations
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!
