Plots of
Red: Hyperbolic Cosecant: csch(x) = 2 / (ex − e−x)
Blue: Hyperbolic Secant: sech(x) = 2 / (ex + e−x)
Green: Hyperbolic Cotangent: coth(x) = (ex + e−x) / (ex − e−x)
Plotted with cubic bézier-curves. The bézier-controll-points are calculated to give a very accurate result. Symbols are embeded in "Computer Modern" (TeX) font.
