COMPLEX(RN,IN,S)

• 'RN' is the real number.
• 'IN' is the imaginary number.
• 'S' is the suffix for the imaginary number.

Description

• COMPLEX function converts the real and imaginary coefficients into a complex number.
• A complex number is a number is in the form z = a + bi, where a and b are real numbers and i is the imaginary unit and $i={\sqrt {-1}}$
• In COMPLEX(RN,IN,SF), here RN is the real part of a complex number,IN is the imaginary part of a complex number and SF is the imaginary unit of a complex number like 'i' or 'j'.
• to mention 'i' and'j' we must use the lower case only
• In a complex number 'z' real part is denoted by Re(z)& imaginary part is denoted by Im(z).
• COMPLEX returns the error value, when RN and IN are non-numeric.
• Suffix 'S' should be either 'i' or 'j', otherwise it shows error value.
• A Complex number whose real part is zero is said to be purely imaginary.
• A Complex number whose imaginary part is zero is a real number.In that cases we have to assign '0' for that part.

• $=COMPLEX(5,2)$ gives $5+2i$
• Failed to parse (syntax error): {\displaystyle =COMPLEX(5,2,"j")} gives $5+2j$
