Decided to use degrees once?
Lent the calculator to a friend?
Pressed a random button as you picked it up?

Use it again next week - your calculation is wrong.
Debug it - your SIN is wrong.
Oh yes, I need to remember to keep resetting the calculator.
Where's the mode switch I hardly ever use?

Much easier to call SINR or SIND assuming you have a programmable or they are both predefined and know they will both work, without needing any mode. Except you then need 3 extra keys on the keypad.

Well... if you take the trouble of doing what Bob suggested, then you could put a STARTUP program that forces the machine to RAD mode every time you warmstart, and another one that does it when you turn it OFF. Then you have fully implemented ijabbott's idea with no drawbacks.
