Homework Statement
Solve sin(z)=2.
Homework Equations
sin z=(e^i*z - e^-i*z)/2*i
sin z=sin x * cosh y + i*cos x * sinh y (haven't tried this way yet)
The Attempt at a Solution
Starting with the first relevant equation, I got z=pi*(1/2 + 2*n) + i*ln(2+sqrt(3)).
The book says that another solution is z=pi*(1/2 + 2*n) - i*ln(2+sqrt(3)).
How do you get that ?
