Good evening, fellow collectors and users,
I recently bought a DM15L and being a complete newbie to the machine I am puzzled because when setting it to degrees DEG I get different answers for sine and cosine of 45 degrees.
Is there any known issue about this topic in any of the firmwares? What can I be doing wrong?
Cheers,
Javier

What answers do you get specifically ?

The same ones I get when I set the angle unit to GRAD. For the sin 0.850903525 and for the cos 0.525321989.

Re: DM15L degrees issue
It sounds like the calculator is in Complex mode. In that mode, the trigs work in radians, regardless of the DEG/RAD/GRAD setting.
Re: DM15L degrees issue
When you set DEG, there should be no annunciator in the bottom of the LCD (vs. "RAD" vs. "GRAD" when those modes are set); is this correct on your machine?
If so, please provide exact key sequences, such as:
[f][FIX][9]
[g][DEG]
[4][5] [SIN] => 0.707106781
[4][5] [COS] => 0.707106781
Also, what version is your ROM?

Re: DM15L degrees issue
Thank you, guys, after a power reset which finished with a Pr Error message is working right. It probably was in complex mode as Thomas guessed. I am kind of embarrassed but for sure it is not the calculator I am used to, and besides I allowed my toddler to mess with it this afternoon although only a few seconds.
Thank you all of you!!
