To write the complex number "i" in exponential form, we can use Euler's formula. Euler's formula states that for any real number theta, e^(i * theta) = cos(theta) + i * sin(theta).
In this case, since we want to write "i" in exponential form, we can set theta equal to pi/2 because it is the angle that "i" forms with the real axis on the complex plane.
Therefore, e^(i * (pi/2)) = cos(pi/2) + i * sin(pi/2).
Evaluating this expression, we have:
e^(i * (pi/2)) = 0 + i * 1.
So, the complex number "i" can be written in exponential form as e^(i * (pi/2)) = i.
This means that "i" can be represented as a complex number with a magnitude of 1 and an argument (angle) of pi/2 in exponential form.
