= sin(re(y))*cos(re(y))/(cos(re(y))^2 + sinh(im(y))^2) + i*sinh(im(y))*cosh(im(y))/(cos(re(y))^2 + sinh(im(y))^2) = (-tan(x) - tan(y) + tan(x + y))/(tan(x)*tan(x + y))

Answer 1

= sin(re(y))*cos(re(y))/(cos(re(y))^2 + sinh(im(y))^2) + i*sinh(im(y))*cosh(im(y))/(cos(re(y))^2 + sinh(im(y))^2) = (-tan(x) - tan(y) + tan(x + y))/(tan(x)*tan(x + y))-tan(x) - tan(y) + tan(x + y) ───────────────────────────── tan(x)⋅tan(x + y)
