SIN(X)^COS(X)

[lrdheat]

In function app, the plot is what I expect...defined over [0,pi),[2pi,3pi), etc. In advanced graphing app, I get an unexpected plot. Over (pi,2pi], I get a plot symmetric to [0,pi) with respect to the y axis, and and another plot of this interval mirrored below the x axis.

Why am I seeing this?

On the July version, (on my iPad) I can trace and display x,y values on this part (what I am expecting to be imaginary numbers) of the graph. On the beta on my physical unit, the plot is as described, but it will not allow me to trace a point on the unexpected part of the plot.
