A.) Eliminate the parameter to find a Cartesian equation of the curve
b.) Sketch the curve and indicate with an arrow the direction in which the cuve is traced as the parameter increases
x= 4 cos t, y= 5 sin t,
-pi/2 (</=) t (</=) pi/2
Parametric Equations, Eliminating the Parameter and Sketching a Curve are investigated. The solution is detailed and well presented.
