HP 41 CX

[Celso Cipolato]

I am so happy! After long years I got back (purchased back) my beloved HP 41 CX that I sold in 2001!! But, I can´t remember how to set the trigonometric functions using radians, degrees or grades. Can someboy help me? Many thanks in advance.

Hi.

You can try:

[XEQ][ALPHA]

D E G

or

R A D

or

G R A D [ALPHA]

This is the direct way. You can also assign these functions to regular keys and use them in [USER] mode, if you want. Note the degrees mode is not signalized while radians and grads have their annunciators.

Hope this helps.

Cheers.
