IMSUB(z1,z2)

• $z1,z2$ are the complex numbers is of the form $a+ib$

Description

• This function gives the difference of the two complex numbers.
• IMSUB(z1,z2), where $z1,z2$ are the complex number is of the form $a+ib$.
• $a$& $b$ are the real numbers. $i$ imaginary unit .$i={\sqrt {-1}}$.

• We can use COMPLEX function to convert real and imaginary number in to a complex number.

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
