IMPRODUCT(z1,z2,z3)

Description

This function gives the product of the complex numbers.
In IMPRODUCT(z1,z2,z3,…), where z1,z2,z3,... are the complex numbers and is in the form of $a+ib$ .
where $a$ & $b$ are the real numbers. $i$ is the imaginary unit . $i={\sqrt {-1}}$ .
The multiplication of two complex numbers is a complex number.
Let $z1=a+ib$ and $z2=c+id$ .
Then the product of two complex number is $z1.z2=(a+ib)(c+id)=(ac-bd)+(ad+bc)i$ .
In this function $z1$ is required. $z2,z3,...$ are optional.
We can use COMPLEX function to convert real and imaginary number in to a complex number.
