" iif "(1-sin A)/(1-cos CA)-(1+sin A)/(1+sec A)=2cot A1600-csc A

(1-sin A) / (1-sec A) - (1 + sin A) / (1 + sec A) = 2cot A (cos A-cos ecA)

Prove that (sin A)/(1 + cos A) + (sin A)/(1 - cos A) = 2 cosec A.

The value of ((sin A)/(1-cos A)+(1-cos A)/(sinA) div ((cot^2 A)/(1+cosec A)+1) is:

Prove that : (sin A)/ (1 + cos A) + (1 + cos A)/ (sin A) = 2 cosec A

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

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

Prove the following identities : (1 + sin A)/ (cosec A - cot A) - (1 - sin A)/ (cosec A + cot A) = 2(1 + cot A)

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

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

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