im confused on this problem: Code: lim tan(7x) x->0 sin(3x) Would I change tan to sin/cos then cancel out the sin and try to evaluate? when i tried on my calc i got 7/3 and i'm confused
lim tan(7x) x->0 sin(3x)

Wow thanks, you just made my life easier, I've been going through my textbook trying to figure this out.
