If one takes ASIN of 2, does it throw an error, or display the complex result? RE: TI Nspire ii (non CAS) - ijabbott - 12-23-2019 11:20 PM 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 RE: TI Nspire ii (non CAS) - Wes Loewer - 12-31-2019 09:02 AM (12-23-2019 08:01 PM)lrdheat Wrote:  How complete is the complex number support on the non CAS TI Nspire ii ?

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"
