Verify the given trigonometric equation — task. Maths CBSE Live product, Class 10 (2026-27).

Answer variants:

\sqrt{\frac{1 + \cos A}{1 - \cos A} \times \frac{1 + \cos A}{1 + \cos A}}

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

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

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

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

\sqrt{\frac{{(1 + \cos A)}^{2}}{1 - \cos^{2} A}}

\sqrt{\frac{1 + \cos A}{1 - \cos A} \times \frac{1 - \cos A}{1 - \cos A}}

Verify that

\sqrt{\frac{1 + \cos A}{1 - \cos A}}

\(=\)

cosec A + \cot A

Proof:

LHS \(=\)

\sqrt{\frac{1 + \cos A}{1 - \cos A}}

\(=\)

cosec A + \cot A

\(=\) RHS
