Answer variants:

\sqrt{\frac{{(1 + \sin θ)}^{2}}{1 - \sin^{2} θ}}

\frac{1 + \sin θ}{\cos θ}

\sqrt{\frac{{(1 + \sin θ)}^{2}}{\cos^{2} θ}}

\sqrt{\frac{{(1 + \sin θ)}^{2}}{1 + \sin^{2} θ}}

\frac{1}{\cos θ} + \frac{\sin θ}{\cos θ}

\sqrt{\frac{1 + \sin θ}{1 - \sin θ} \times \frac{1 + \sin θ}{1 + \sin θ}}

\sqrt{\frac{1 + \sin θ}{1 - \sin θ} \times \frac{1 - \sin θ}{1 - \sin θ}}

Verify that

\sqrt{\frac{1 + \sin θ}{1 - \sin θ}}

\(=\)

\sec θ + \tan θ

Proof:

LHS \(=\)

\sqrt{\frac{1 + \sin θ}{1 - \sin θ}}

\(=\)

\sec θ + \tan θ

\(=\) RHS
