I am working on some calculus homework and I am stumped by this question. It is in the section "derivatives of trigonometric functions." It seems like it should be easy, but I can't think of where to start. I don't need any answers and you don't need to present any calculations, I only need an idea of where to start. Thank you.

How many tangent lines to the curve y=x/(x+1) pass through the point (1,2)? At which points do these tangent lines touch the curve?

2. Relevant equations

I determined the derivative of the curve to be: 1/(x+1)^2

3. The attempt at a solution

I began by finding the derivative (as stated above), but I'm not sure where to go next. Thanks.
