Asked by Mary
I really need help. Create an appropriate table of values for the function f(x)=tan3x/7x and use the reslut to estimate lim as x approaches 0 tan3x/7x

I'm sure you can make the table.
You know that sinu/u -> 1 as u ->0
since cos(0) = 1, that means that
tanu/u -> 1 as u -> 0
You have
tan3x/7x = tan3x / (3x)*(7/3)
= (tan3x/3x) * 3/7
so, what do you think the limit is?
