IMCOS (ComplexNumber)
- 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
- x & y are the real number
- 'i' is the imaginary unit
- Also x is called the real part & y is the imaginary patr of a complex number.
- COMPLEX is the function used to convert Real & Imaginary numbers in to a complex number.
- is defined by
is defined by
