HP 41 CX Message #1 Posted by Celso Cipolato on 30 Sept 2012, 5:52 p.m. 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.

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. Luiz (Brazil) Edited: 30 Sept 2012, 6:14 p.m.
