The 35s has no problem with cos(3i), while the TI84 gives "error data type" even in complex mode. You can get the same result using cosh(3) or (e^3+e^-3)/2. I found that mildly interesting.

Like the HP-35s, the HP-32S, HP-32SII, and HP-33s can also take cos(3i) -- and cannot take cos-1(3i) or hyperbolics of (3i) -- because these functions offer the same domain for complex-valued input on each model. The functionality was apparently based on the HP-41 Math Pac of 1980, as I've posted before. The HP-15C, HP-42S, and all RPL-based models offer full domain for mathematical functions for which complex-valued arguments are defined. This would include the HP-28C/S and HP-49G, as well. -- KS
