IMARGUMENT(Complexnumber)

• $Complexnumber$ is of the form $z=x+iy$.

Description

• This function gives the principal value of an argument of a complex-valued expression $z$.
• i.e The angle from the positive axis to the line segment is called the Argument of a complex number.
• In this function angle value is in Radians.
• Here $IMARGUMENT(Complexnumber)$, Where Complexnumber in the form of $z=x+iy$. i.e $x$ & $y$ are the real numbers.
• $I$ imaginary unit .$i={\sqrt {-1}}$.
• An argument of the complex number $z=x+iy$ is any real quantity $\phi$ such that $z=x+iy$ = $rcos(\phi )+irsin(\phi )$ for some positive real number 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 r} .

• To change the Radian value to Degree we can use DEGREES function or we can multiply the answer with 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 \frac{180}{\pi}} .
• We can use COMPLEX function to convert real and imaginary number in to a complex number.
