y_(y)=(cos A-sin A+1)/(cos A+sin A-1)=csc A+cot A," using the identity const."

(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 ) = 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

Prove the following identities, 0^(@) le theta le 90^(@) . (v) (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

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

Prove that (cos theta-sin theta+1)/(cos theta+sin theta-1)=csc theta+cot theta

(1+tan A)/(sin A)+(1+cot A)/(cos A)=2(sec A+cosec A)
