Hello.i want animate the circle of radius 2 on the parabola y=x^2-30*x in the interval [-1,2].I wrote like that =animate(plot,[[-30*t+2cos(Phi),t^2+2sin(Phi)],Phi=0..2*Pi],t=-2..1) .But it doesn't work.What is wrong?

hi.my program is this=

a:=[[2.5,0.05],[-2.5,1],[0,1],[-1.5,1],[-1,2],[1,2],[1.5,1],[0,1],[2.5,1],[2.5,0.05],[-2.5,0.05]]

plot(a)

r:=plot(a)

b:=[[0,2],[0,1]]

plot(b)

v:=plot(b)

c:=plot([-1+1/2*sin(t),1/2*cos(t),t=0..2Pi],scaling=constrained])

d:=  plot([1+1/2*sin(t),1/2*cos(t),t=0..2Pi],scaling=constrained]) ...

Hi.i want to draw the picture which is in this SITE http://www.resurs.az/thumbnail.php?file=Qafqaz_Uni_370925279.jpg&size=article_medium  .Please help me...
