x21 = -2 + cos(1/2 + re(x1))*cosh(im(x1)) - I*sin(1/2 + re(x1))*sinh(im(x1))
$$x_{21} = - i \sin{\left(\operatorname{re}{\left(x_{1}\right)} + \frac{1}{2} \right)} \sinh{\left(\operatorname{im}{\left(x_{1}\right)} \right)} + \cos{\left(\operatorname{re}{\left(x_{1}\right)} + \frac{1}{2} \right)} \cosh{\left(\operatorname{im}{\left(x_{1}\right)} \right)} - 2$$
x21 = -i*sin(re(x1) + 1/2)*sinh(im(x1)) + cos(re(x1) + 1/2)*cosh(im(x1)) - 2
