IMSUB(Complexnumber1,Complexnumber2)

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

Description

• This function gives the difference of the two complex numbers.
• In $IMSUB(Complexnumber1,Complexnumber2)$, where Complexnumbers are of the form $z=a+ib$.
• $a$& $b$ are the real numbers. $i$ imaginary unit .$i={\sqrt {-1}}$.
• Let $z1=a+ib$ and $z2=c+id$.
• The difference of two complex number is:$(a+ib)-(c+id)=(a-c)+(b-d)i$ where $a,b,c$ and $d$ are real numbers.
• We can use COMPLEX function to convert real and imaginary number in to a complex number.

ZOS Section

• The syntax is to calculate the difference of the complex numbers in ZOS is $IMSUB(Complexnumber1,Complexnumber2)$.
  • $Complexnumbers$ are of the form $z=a+ib$
• For e.g.,IMSUB("4+5i","9-3i")

Examples

1. IMSUB("6+4i","5+3i")=1+1i
2. IMSUB("3+4i","6+7i")=-3-3i
3. IMSUB("8","9+10i")=-1-10i
4. IMSUB("5+7i","3")=2+7i
