If sec θ + tan θ = p ; (p > 1) ; then value of \(\frac{cosec θ + 1}{cosec θ - 1}\) is? |
2p + 1 \(\frac{p}{2p + 1}\) p2 1 - 2p |
p2 |
Put p = 3 sec θ + tan θ = 3 sec θ - tan θ = \(\frac{1}{3}\)
⇒ 2sec θ = \(\frac{10}{3}\) ⇒ sec θ = \(\frac{5}{3}\) then cosec θ = \(\frac{5}{4}\) \(\frac{cosec θ + 1}{cosec θ - 1}\) = \(\frac{\frac{5}{4} + 1}{\frac{5}{4} - 1}\) = 9 or p2 |
