gives the hyperbolic cosine integral Chi(z).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • , where gamma is Euler's constant.
  • CoshIntegral[z] has a branch cut discontinuity in the complex z plane running from - to 0.
  • For certain special arguments, CoshIntegral automatically evaluates to exact values.
  • CoshIntegral can be evaluated to arbitrary numerical precision.
