Hello,

I noticed an irregularity in the calculation of the inverse trigonometric functions. Look at the pictures:



This is the version 0.89 SMath Studio. Version 0.87 is calculated correctly.

Thanks.

Please, do not use Angles global option of the program (it is obsolete and will be removed from the next SMath Studio version). Set Angles to radians and then use degree unit instead:


See also degrees / radians topic.
