where 'ComplexNumber' is any complex number of the form x+iy.
- IMCOS(), returns the cosine of a complex number.

Description

This function gives the cos value of any complex Number.
Consider the complex number in the form of Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle x+iy}
x & y are the real number
'i' is the imaginary unit Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle i=\sqrt{-1}}
Also x is called the real part & y is the imaginary patr of a complex number.
