That should work.

Yo
Ah
So I just multiply by pi over 180?
Cheers!

According to the doc:
http://code.google.com/android/reference/java/lang/Math.html#sin(double)
you need to provide the angle in radians, where 2*Pi corresponds to
360 degrees (i.e. Pi/2 is 90 deg).
http://en.wikipedia.org/wiki/Radian
In Java, you can use the constant Math.PI for Pi.

V/sintest (21227): -0.8011526357338304
And that's Sin(180) ?
