Help with Equation of a Circle y=sqrt(r**2 + x**2)

[Kuntzy]

I was wondering if anyone knew how to get a line to move around the screen like clock.
All have thus far is:

var r: real:= 200
var mx:int:=1
var my:int:=1

loop

mx+=1
my+=1

var y:real:= sqrt(r**2 + mx**2)
var x:real:= sqrt(r**2 + my**2)

drawline(320, 150, round(x), round(y),black)
delay(30)
cls
end loop

Once I get this i working i want to make a gambling game and would use this to make the ballspin around the table. [/b]

use trig.

code:

for i : 0 .. 360 by 2     drawline (maxx div 2, maxy div 2, maxx div 2 + round (80 * cosd (i)), maxy div 2 + round (80 * sind (i)), 7)     drawoval (maxx div 2, maxy div 2, 83, 83, 7)     delay (40)     cls end for

oh yeah, trig pwnz 8) Calculus too, although I haven't used it in programming just yet...

Thanks for your help, the code worked great :D
