Abstract: Mechanical devices for tracing curves offer a tangible approach to geometry, complementing symbolic abstraction with physical construction. Starting from the historical machine for the real exponential, we introduce a planar mechanism that solves f = f ‘ in the complex domain, with a natural extension of the real case. To enhance accessibility and visualization, the behavior of the machine is illustrated using Dynamic Geometry simulations.
Keywords: complex exponential, mathematical machines, history of scientific instruments, dynamic geometry system, mathematics education.
