(732, #47) Find parametric equations for the tangent line to the curve
with the parametric equations at the point (0, ¼, 1).

Solution:

The parameter corresponding to the point (0, ¼, 1) is t = ¼, so

So the parametric equations for the tangent line to the curve
with parametric equations at the point (0, ¼, 1) are:
