suppose i have this circle: drawoval (100,100,10,10,16) and this dot: drawdot(100,110,16) how do i make the dot move around on the circumference of the circle? |

you could abuse a recursive flood fill's code... or you could just use the equation of a circle and solve for X and Y, write some code to keep track of negative and positive's as both are resulted. |

If you have the hypotenuse and angle, which trigonometry function(s) would you use? I'll give you a hint, it is not tan. |
