Prove that sqrt((cosec A + 1)/(cosec A - 1)) - sqrt((cosec A - 1)/(cosec A + 1)) = 2tan A

Prove that (sin A +cosec A) ^(2) +(cos A +sec A) ^(2) =7+ tan ^(2) A +cot ^(2) A

If A is not an integral multiple of (pi)/(2) , prove that (i) tan A + cot A= 2 cosec 2 A (ii) cot A - tan A = 2cot 2A

Prove that (sin theta - cos theta + 1)/(sin theta + cos theta - 1) = (1)/(sec theta - tan theta) using the identity sec^(2) theta = 1 + tan^(2) theta .

Prove that (sin theta -cos theta+1 )/( sin theta + cos theta -1) =(1)/( sec theta -tan theta ) [use the identity sec ^(2) theta =1 +tan ^(2) theta ]

("cosec " theta - sin theta ) ( sec theta - cos theta ) ( tan theta + cot theta ) =
