TI Nspire ii (non CAS) - lrdheat - 12-23-2019 08:01 PM
How complete is the complex number support on the non CAS TI Nspire ii ? If one takes ASIN of 2, does it throw an error, or display the complex result?

The reference guide shows an example with a complex matrix result for the matrix inverse sine of a square matrix, so I should think it should also be able to handle the inverse sine of a real or complex scalar.

Exactly like in the TI 86, TI 89, both machines without Complex mode if I remember

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 calculationand then returns: "Error: 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.
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 errorand then returns: "Error: Domain error"
An argument must be in a specified domain.
