Coshbx
Coshbx is a mathematical function that represents the hyperbolic cosine of a complex variable. It is a fundamental function in complex analysis and is closely related to the hyperbolic cosine function for real numbers. The function is defined for a complex number *z* = *x* + *iy*, where *x* and *y* are real numbers, and *i* is the imaginary unit.
The hyperbolic cosine of a complex number *z* is expressed as:
This formula extends the real-valued hyperbolic cosine function to the complex plane. When *z* is purely real
Coshbx is not a commonly used notation in mathematics, as the standard notation for hyperbolic cosine is
Cosh(*z*) has applications in various fields, including quantum mechanics, special relativity, and the study of waves
