TI Nspire graph Question

[lrdheat]

Interestingly, on the Prime (CAS), taking TAN (-.6) and SIN (-.6) both yield non complex results...if I take the result for TAN (-.6) and raise it to the result of SIN (-.6), a non complex result comes up. However, if I type in TAN(-.6)^SIN(-.6), I get a complex result!

The Prime plots the non complex portion of the graph in Function App, and the real and complex portion of the graph in the Advanced Graph App...the Prime does not attempt to connect the dots, and has an uncluttered graph, but was still surprised that the complex portion of the graph appeared.

The CASIO fx-CG 50 plots only the real portion of the graph.
