Question

Plz solve t for e fastly as u can plz help me

Answer 1

Answer:

Step-by-step explanation:

1$\frac{x}{y}$$\frac{1}{sec - tan} = \frac{1}{sec - tan}  * \frac{sec + tan}{sec + tan}  = \frac{sec + tan}{secx^{2}  - tanx^{2} }$

using identity,

$1 + tanx^{2}  = secx^{2}$

and it should be done.
