Answer variants:

\frac{(1 - \cos A) (1 - \cos A)}{(1 - \cos A) (1 + \cos A)}

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

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

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

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

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

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

Verify that

{(cosec A - \cot A)}^{2}

\(=\)

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

Proof:

LHS \(=\)

{(cosec A - \cot A)}^{2}

\(=\)

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

\(=\) RHS
