I have a curve Tractrix: x(t)=1/cosht,y(t)=t-tanht
how I do?
- Find the length of the tangent line from the tangent point to the asymptote
- find the area between the curve and its asymptote
- find the length of the curve from x-axis to a point on the curve
- find the slope of the tangent line at any point along the curve
I hope you can help , its very important to me
