Question

Please help me with the following problem. I am asked to find parametric equations of the line tangent to the graph of r(t) at the point where t=t0.
r(t)=t^2i+(2-lnt)j
t0=1

Answer 1

I found the vector of the tangent line is <2,-1> and the initial point of the vector is (1,2). How do I find a parametric equation for the tangent line given this information?
