Note that i=√-1 is an imaginary complex number. The square root of i is equal to ±(1+i)/√2. In this post, we will learn how to find the square root of i.
What is the Square Root of i
We have:
=
=
=
So we have obtained that
Now, taking the square root on both sides will give us the square root of i. That is,
So the value of the square root of i, that is, the square root of iota is equal to ±(1+i)/√2. We write it as follows:
Square Root of i in Polar Form
We know that the polar form i is equal to
We take square root on both sides. Thus,
∴
= ± [cos(π/4) + i sin(π/4)]
= ± [1/√2 + i/√2]
= ±(1+i)/√2.
Therefore, the value of square root of i is equal to ±(1+i)/√2 and this is obtained by using the polar form of a complex number.
