Question

If :
$\boxed{ \begin{array}{cc}\sf \bull \: x = asec \theta \: cos \phi \\ \\ \sf\bull \: y = bsec \theta sin \phi \: \: \\ \\ \sf \bull \: z = ctan \theta \: \: \: \: \: \: \: \: \: \: \end{array}}$
⠀
Then find the value of :
$\boxed{ \sf \: \dfrac{ {x}^{2} }{ {a}^{2} } + \dfrac{ {y}^{2} }{ {b}^{2} } }$​
