[#0%414001" cosec' "A=1+cot^(2)A" and "CH^(2)d" and "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

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

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

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

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

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

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

Prove that , (Cot A-cos A)/(cot A+cos A)=(cosec A-1)/(cosec A+1)
