IMSUB(z1,z2)

• Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 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 in the form of $a+ib$.
• $a$& $b$ 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.

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
