Chi​(AngouriMath.​Entity)

 Method (no overloads)

Summary

The hyperbolic cosine integral, Chi(z) = gamma + ln z + int_0^z (cosh t - 1)/t dt

Parameter "a"

The argument, any complex number but 0

Returns

The Chif node

Remarks

Real on x > 0, so what int cosh(x)/x dx is in closed form; its cut is the
negative real axis, Chi(-x) = Chi(x) + i pi.
