Answer 1

Answer:

p^2 + 1 / p^ - 1

Step-by-step explanation:

we know that if sec x - tan x = p

then    sec x + tan x = 1/p                                         since sec^x - tan^ x = 1

if we sub two equations

- 2 tanx = p - 1/p

tan x = p^ - 1 / 2p                                                   tan x = opp / adj

so sin x will be p^ - 1 / p^ + 1                                   sin x = opp / hyp

so cosec x = p^ + 1 / p ^ - 1                        so hyp = p^+ 1  [ root ( opp^2 + adj^2 )]
