TI-nspire CX II (non-cas), OS ver 5.1.0
In Real Mode asin(2) pops up an error message box that says:

Quote:Non-real calculation

For example, if the software is in the Real setting, √(-1) is invalid.
To allow complex calculations, change the "Real or Complex" Mode Setting to RECTANGULAR or POLAR.

and then returns: "Error: Non-real calculation"

In Rectangular, Radians mode, it returns 1.5707963267949-1.3169578969248*i

In Rectangular, Degrees/Gradians mode it pops up an error message box that says:

Quote:Domain error

An argument must be in a specified domain.

and then returns: "Error: Domain error"
