Extracts a segment of text starting from a specific character and extending for a defined number of bytes.
Calculates the hyperbolic sine of a specified complex number. For instance, inputting a complex number “x+yi” will yield “sinh(x+yi).”
Calculates the hyperbolic cosine of a specified complex number. For instance, a complex number in the form “x+yi” will yield “cosh(x+yi).”
