add the 15C, 42S, 48G, and 50G to the list of HP's that have no trouble taking the cos(3i)!
Like the HP35s, the HP32S, HP32SII, and HP33s can also take cos(3i)  and cannot take cos^{1}(3i) or hyperbolics of (3i)  because these functions offer the same domain for complexvalued input on each model.
The functionality was apparently based on the HP41 Math Pac of 1980, as I've posted before.
The HP15C, HP42S, and all RPLbased models offer full domain for mathematical functions for which complexvalued arguments are defined. This would include the HP28C/S and HP49G, as well.
