Solve tanztanz=seczcscz

$$\tan z \tan z = \sec z \csc z$$

Solve for z

$$z=\pi +2\pi n_{13}+arcSin(\frac{1}{18}\left(34012224+1889568\times 18^{\frac{2}{3}}\left(-9+93^{\frac{1}{2}}\right)^{\frac{1}{3}}+\left(-1889568\right)\times 18^{\frac{2}{3}}\left(9+93^{\frac{1}{2}}\right)^{\frac{1}{3}}\right)^{\frac{1}{6}})\text{, }n_{13}\in \mathrm{Z}$$

$$z=arcSin(\frac{1}{18}\left(34012224+18^{\frac{17}{3}}\left(-9+93^{\frac{1}{2}}\right)^{\frac{1}{3}}+\left(-1\right)\times 18^{\frac{17}{3}}\left(9+93^{\frac{1}{2}}\right)^{\frac{1}{3}}\right)^{\frac{1}{6}})+2\pi n_{16}\text{, }n_{16}\in \mathrm{Z}$$
