Consider the curve C given in parametric equations as
{
3t?et
C :
4 arctan(t)
(a) Find the tangent and the normal lines to the curve at the point of the curve corresponding to t = 1.
(Note: you do know what the exact value of arctan(1) is.)
(b) Find the points on the curve at which the curve has a vertical tangent line, and the points at which
it has a horizontal tangent line. (Note: in class, we did mention how to find the values of t for
which a curve C with parametric equations has vertical or horizontal tangent line.)
dx
(c) Find an expression for
dy
(that is, the derivative x'(y(t))).
-(y(t)), the (implicit) derivative of x with respect to y, as a function of t
