IMSQRT(z)

Description

This function gives square root of a complex number.
IMSQRT(z), Where z is the complex number is in the form of "x+iy".
where x&y are the real numbers.'i' imaginary unit . $i=sqrt{-1}$ .
The square root of a complex number is defined by Failed to parse (syntax error): {\displaystyle \sqrt{z}=\sqrt{x+iy}=\sqrt{r.e^iθ}=\sqrt(r)(cos(θ/2)+isin(θ/2)} ,where r is the modulus of z. $r={\sqrt {x^{2}+y^{2}}}$ and θ is the argument of z.Failed to parse (syntax error): {\displaystyle θ=tan^-1frac{y/x}} also θ∈(-Pi(),Pi()].
We can use COMPLEX function to convert real and imaginary number in to a complex number.

Description

This function calculates the square root of a complex number in a + bi or a + bj text format.

IMSQRT

The square root of a complex number is:

IMSQRT(IN)

where IN is the complex number

Let's see an example

I.e =IMSQRT(“2+i”) is 1.4553+0.34356i
