The IMCOS () is an engineering function which takes ‘inumber’ as an argument and returns the cosine of the given complex number in the text format of x+yi or x+yj.
Formula:
=IMCOS (inumber) In the above syntax, the argument inumber denotes the complex number for which you want the cosine value.
Video Tutorial:
Let us see how the IMCOS function returns the cosine of complex numbers with the help of the below video.
