Hi, firstly i am confused as to what tan(z) is. Is it just tan(x+iy) and how do i find the real and imaginary parts of it? From this how do i find the solutions to tan(z) = 0?

Thanks.

Could i not just use sin(z)=sin(x+iy) so Re(sin(z))= sin(x)cosh(y) and Im(sin(z)) = cos(x)sinh(y) and do the same for cos(x+iy) and then find the real and imaginary parts of tan(z) that way?
