Hello everyone :)
I have a slight problem with my calculator.
I want to calculate the angle of alpha so I want to use the Arcsin key.
To do this I enter "Arcsin(1.26)" and when I press the "EXE" key an error message appears. The same goes for Arccos and Arctan.
I don’t know what to do if someone has an idea please let it be known :)

Hello,

I would like to remind you that a sine or a cosine has values between -1 and 1 (including the bounds)

So it is not surprising to receive an error message when typing Arcsin (1.26); the same goes for Arccos

However, with Arctan, there should be no error message.

Best regards
