prove that: cotA-cosA/ cotA +cosA = cosecA-1/cosecA+1

\frac{cot A - cos A}{cot A + cos A} = \frac{cos e c A - 1}{cos e c A + 1}

Prove the following trigonometric identities:

$\frac{c o t A - c o s A}{c o t A + c o s A} = \frac{c o s e c A - 1}{c o s e c A + 1}$

\sqrt{\frac{1 - cos A}{1 + cos A}} = c o s e c A - cot A

\frac{c o t A + c o s e c A - 1}{c o t A - c o s e c A + 1} = \frac{1 + c o s A}{s i n A} = c o s e c θ + c o t θ = \frac{s i n A}{1 - c o s A}
