Inputs/Outputs

  • cdbl.png x —

    x is the input argument. If x is negative, the VI uses the absolute value of x.

  • idbl.png Chi(x) —

    Chi(x) returns the value of the hyperbolic cosine integral.

    • The following equation defines the hyperbolic cosine integral function.

    where γ is Euler's constant.
