int_(cos A+sin A-1)^(+oo)(cos A-sin A+1)/(cosec A+cot A)=cos A

(cos A-sin A + 1) / (cos A + sin A-1) = csc A + cot A

Prove that: (cos A - sin A + 1)/(cos A + sin A -1) = "cosec"A + cot A

prove that (cos A-sin A + 1) / (cos A + sin A-1) = cos ecA + cot A

( cos A - sin A + 1 ) / ( cos A + sin A - 1 ) = cosec A + cot A cosec A + cot A , = using the identity cosec ^ 2 A = 1 + cot^ 2 A .

Prove the following identities, 0^(@) le theta le 90^(@) . (v) (cos A - sin A +1)/(cos A + sin A -1) = cosec A + cot A

Prove that : (1)/ (cos A + sin A - 1) + (1)/ (cos A + sin A + 1) = cosec A + sec A

(cos A-sin A+1)/(cos A+sin A-1)=cosec A+cot A," using the identity cosec^(2)A=1+cot

Prove that :(1+cot A+tan A)(sin A cos A)=sin A tan A cot A cos A

Prove that (sin A)/(sec A + tan A -1)+ (cos A)/("cosec "A +cot A-1)=1
