Sketch the graph of the parametric curve given by r = -3t, y = -302. Find the points where the tangent to the graph is vertical or horizontal. 6. (a) On the ry-coordinate system sketch the graph of the parametric curve (astroid) given by the equations x - a cos" 0, y - asin 0, where a > 0. (b) Find the total length of this curve.

5)
Tangent is vertical
t = 1; x= -2; y=-2
t= -1; x = 2; y= -4
Tangent is horizontal
t = 0; x= 0; y=0
t= 2; x = 2; y= -4
6) The total length of the curve is L = 6a.
