hey again....

I made a drawparabola command

code:
procedure drawparabola (x:int,y:int,xlen:int,ylen:int,col:int)
  var xn,yn:real
  for t:1..10000
    xn:=0.5*xlen* sin (t)+x
    yn:=0.5*ylen* cos (2*t)+y-round(0.5*ylen)
    drawdot(round(xn),round(yn),col)
  end for
end drawparabola

drawparabola(100,100,50,60,45)
drawbox(99,99,101,101,54)       
drawbox(75,40,125,40,78)
drawbox(75,40,75,100,78)



Okay, information about this, as the box's which are really lines, but I'm to lazy to change it shows.......xlen is the horizontal length of the parabola at its widest point. ylen is the maximum height of the parabola, x,y is the vertex.


I don't technically know for sure that its a parabola, but it looks like one...and meh
