 CONVERT RADIANS TO DEGREES AND DEGREES TO RADIANS
 radians = degrees * Math.PI / 180
 degrees = radians * 180 / Math.PI
 
 ROTATE TO THE MOUSE (OR ANY POINT)
 dx = mouseX - sprite.x;
 dy = mouseY - sprite.y;
 sprite.rotation = Math.atan2(dy, dx);
 
 GET THE DISTANCE BETWEEN TWO POINTS
 dx = x2 - x1;
 dy = y2 - y1;
 dist = Math.sqrt(dx*dx + dy*dy);
 
 CONVERT ANGULAR VELOCITY TO X, Y VELOCITY
 vx = speed * Math.cos(angle);
 vy = speed * Math.sin(angle);
 
 CONVERT ANGULAR ACCELERATION (ANY FORCE ACTING ON AN OBJECT) TO X, Y
 ACCELERATION
 ax = force * Math.cos(angle);
 ay = force * Math.sin(angle);
