### reverse function of latex()

Hi imagine I got this Latex expression from wikipedia: z_k = 2 \sqrt{\frac{-p}3} \cos{\left(\frac13\arccos{\left(\frac{-q}2\sqrt{\frac{27}{-p^3}}\right)}+ \frac{2k\pi}3\right)}\qquad\mbox{ avec }\qquad k\in{0,1,2}

is there a reverse function kind of retro-latex(z_k = 2 \sqrt{\frac{-p}3} \cos{\left(\frac13\arccos{\left(\frac{-q}2\sqrt{\frac{27}{-p^3}}\right)}+ \frac{2k\pi}3\right)}\qquad\mbox{ avec }\qquad k\in{0,1,2}) which will gives me the expression in classical form (not in Latex) ?

is there a reverse function kind of retro-latex(z_k $$z_k = 2 \sqrt{\frac{-p}3} \cos{\left(\frac13\arccos{\left(\frac{-q}2\sqrt{\frac{27}{-p^3}}\right)}+ \frac{2k\pi}3\right)}\qquad\mbox{ avec }\qquad k\in{0,1,2}) k\in{0,1,2}$$

Is there a reverse function kind of

unlatex(z_k = 2 \sqrt{\frac{-p}3} \cos{\left(\frac13\arccos{\left(\frac{-q}2\sqrt{\frac{27}{-p^3}}\right)}+ \frac{2k\pi}3\right)}\qquad\mbox{ avec }\qquad k\in\{0,1,2\})


which will gives me the expression in classical form (not in Latex) ?Latex)?
