1.) Consider the following.

x = sin(1/2) , y = cos(1/2) ,

(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 curve is traced as the parameter increases.

2.) Consider the following.

x=sin() , y=cos() , 0

(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 curve is traced as the parameter increases.
