Polar Coordinates and Analog Clock Help

[Charles Conlow]

Greetings all! I've hit a brain bump here and need a boost...
given this analog clock code (just the hour hand here), where am I missing
the math to move the hour hand along PAST this point? Using this code, it's
drawn AT the hour position, but not PAST it as a real clock does. I'm
thinking too hard about this, perhaps?

Thanks!
Chuck

// draw the HOUR HAND (busted!)
float x_hour = centerx + (int)((centerx * .60) * Math.Sin(2 * Math.PI *
(double)currentTime.Hour / 12));
float y_hour = centery - (int)((centery * .60) * Math.Cos(2 * Math.PI *
(double)currentTime.Hour / 12));
e.Graphics.DrawLine(new Pen(Color.Black,4), centerx, centery, x_hour,
y_hour);

not tested but I think where it has "currentTime.Hour / 12" (which essentially
is the degree) you'd need to add how many minutes / 60 so you don't get an
even 12th. So....

(double)currentTime.Hour / 12 + (double)currentTime.Minute / 60

if that doesn't work then somewhere you have to add the minutes

Thanks... I had been staring at that silly bit of code for too long. Your
response was right on! Simply adding in the additional degree(s) for the
minutes worked perfect. Thanks again!
