(i) \sqrt{\frac{1 + \sin θ}{1 - \sin θ}} = (\sec θ + \tan θ) (ii) \sqrt{\frac{1 - \cos θ}{1 + \cos θ}} = (cosec θ - \cot θ) (iii) \sqrt{\frac{1 + \cos θ}{1 - \cos θ}} + \sqrt{\frac{1 - \cos θ}{1 + \cos θ}} = 2 cosec θ

\frac{(1 + sin θ) (1 - sin θ)}{(1 + cos θ) (1 - cos θ)}

tan θ = \frac{4}{3}

tanθ = \frac{3}{4}

\tan θ = \frac{20}{21}

\frac{1 - \sin θ + \cos θ}{1 + \sin θ + \cos θ} = \frac{3}{7}

tan θ = \frac{3}{4}

\frac{1 - cos θ}{1 + cos θ}
