Homework Statement
Show that
(a) log(i^2) = 2*log(i) when log z=ln r + i * theta (r>0 and pi/4 < theta < 9*pi/4)
(b) log(i^2) <> 2*log(i) when log z=ln r + i * theta (r>0 and 3*pi/4 < theta < 11*pi/4)
Homework Equations
log z = ln r + i * theta
The Attempt at a Solution
Got log(i) = i * pi/2
log(i^2)= i * pi.
Are those right ?
Do not know what to do with ranges given for theta.
