Homework Statement
Show: sinh(z + i2(pi)) = sinh(z) using sinh(z) = (ez - e-z)/2
Homework Equations
The Attempt at a Solution
So far I have (ex + i(2∏+y) - e-(x+i(2∏+y))/2.
Need help proceeding from here. My thoughts were to define a z' = x + i(2∏+y) but I don't think that I can then say that it is equal to sinh(z) but rather sinh(z').
