lim tanx/x = 1

x->0

## The Attempt at a Solution

We just began working with limits, and we haven't covered much of trig functions at all, but our prof gave us these 2 questions to see what we can do with them. I really don't know how to begin with them.

For the first problem i tried to answer it by splitting it into 2 fractions: sin3x/x * sin3x/x then sin3x/3x * sin3x/3x * 9/1 which gave me the answer 9 for it. I'm not sure if that's right though.

I have no clue how to start on the second one. :(
