Tetraviews of Elementary Functions
The natural living space of a function with being a complex variable is the two‐dimensional complex space with coordinates or the four‐dimensional real space with coordinates . This Demonstration shows three‐dimensional projections from the four‐dimensional space. By carrying out rotations in the four‐dimensional space, different views of the function can be obtained (including views of the inverse function ).
