what is i^-i

OpenStudy (nirmalnema):

plz explain all the steps

OpenStudy (phi):

i can be written as \( \cos\left(\frac{\pi}{2}\right) + i \sin\left(\frac{\pi}{2}\right) \) or in polar form as \( e^{i\frac{\pi}{2} } \) raise it to the -i th power: \( \left(e^{i\frac{\pi}{2} } \right)^{-i}\) use the rule \( \left(a^b\right)^c = a^{bc} \) to simplify

OpenStudy (nirmalnema):

plz...further simplify it /// @phi

OpenStudy (phi):

are you asking what is -i * i * pi/2 ?

OpenStudy (nirmalnema):
