How to you compute Trig functions in radians on the HP71B?

That actually saves a keystroke since the closing parenthesis is automatically inserted for you. I knew this worked when manually inserting parenthesis in your formula, but didn't know it did so for functions as well. Maybe if I used CALC mode, I'd recall such details...
