| The Polar-Planimeter is an analogue mechanical mathematical instrument. It allows to compute the area inclosed by a curve and also the integral of a function (which is the area between the function y = f(x) and the x axis). The invention of the planimeter is attributed to the Bavarian engineer Hermann in 1814. Manual in German here . | |
