Answer 1

Please put your School SUBJECT in the School Subject box so the proper tutor will see your post and be able to help you. The name of your school is not the School SUBJECT. Examples: math, calculus, history, language arts, etc.

Answer 2

assuming you mean i = √-1, then since

i = 1 cis π/2,
i^i = 1 cis (π/2 i)
= cos(π/2 i) + i sin(π/2 i)
= cosh(π/2) - sinh(π/2)
= e^(-π/2)
