The application of hyperbolic functions to electrical engineering problems; being the subject of a course of lectures delivered before the University of London in May and June 1911
A printed course of lectures by electrical engineer Arthur E. Kennelly, delivered at the University of London in 1911 and published there in 1912 for engineers and mathematics students working with hyperbolic functions. The plates are line diagrams: labelled circles, arcs, tangents and radial grids plotting loci of tanh and sinh, with dashed construction lines, small point letters and set equations alongside.
