IMPRODUCT(Complexnumber1,Complexnumber2)

• $Complexnumbers$ are of the form $z=a+ib$

Description

• This function gives the product of the complex numbers.
• In $IMPRODUCT(Complexnumber1,Complexnumber2)$, where Complexnumbers are in the form of $z=a+ib$.
• where $a$ & $b$ are the real numbers. $i$ is the imaginary unit .$i={\sqrt {-1}}$.
• In CALCI we can find the product of 2 to 29 Complex numbers.
• 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.

ZOS Section

• The syntax is to calculate product of the complex numbers in ZOS is $IMPRODUCT(Complexnumber1,Complexnumber2)$
  • $Complexnumbers$ are of the form $z=a+ib$
• For e.g., improduct("2+3i","4+5i","8+7i","10-14i")

Examples

1. =IMPRODUCT("1+3i","5+2i") = -1+17i
2. =IMPRODUCT("i","3-i") = 1+3i
3. =IMPRODUCT("5","-2+4i") = -10+20i
4. =IMPRODUCT("2+3i","4+6i","3+5i") = -150+22i
5. =IMPRODUCT("-6-2i","-1-i") = 4+8i
