Parametric Equations : Find the vertex, focus , directrix
Not what you're looking for?
1.) Find the vertex, focus , directrix of the parabola and sketch its graph
y+ 12x - 2x^2 = 16
2.) Sketch the curve by using parametric equations to plot points. Indicate with an arrow the direction in which the curve is traced as t increases
x= 2 cos t, y= t- cos t, (0 (</=) t (</=) 2 pi)
