A motorboat starts at the origin and moves in the direction of the positive x-axis, pulling a waterskier along a curve C called a tractrix. See the figure below. The waterskier, initially located on the y-axis at the point (0, a), is pulled by a rope of constant length a that is kept taut throughout the motion. At time t > 0 the waterskier is at point P(x, y). Assume that the rope is always tangent to C. Use the concept of slope to determine a differential equation for the path C of motion.

Question
A motorboat starts at the origin and moves in the direction of the positive x-axis, pulling a waterskier along a curve C called a tractrix. See the figure below.
The waterskier, initially located on the y-axis at the point
(0, a),
is pulled by a rope of constant length a that is kept taut throughout the motion. At time
t > 0
the waterskier is at point
P(x, y).
Assume that the rope is always tangent to C. Use the concept of slope to determine a differential equation for the path C of motion.y′ = ?
