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

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

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

7. (sin A+cos A)(cot A+tan A)=sec A+cosec A

sin A(1+tan A)+cos A(1+cot A)=sec A+cosec A

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

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

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