" (ii) "(tan A+sec A-1)/(tan A-sec A+1)=(1+sin A)/(cos A)

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

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

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

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)

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

Prove that (i) (sec 8A -1)/(sec 4A -1) =(tan 8A)/(tan 2A) (ii) (cos A+ sin A)/(cos A - sin A)-(cos A-sin A)/(cos A+sin A)=2 tan 2A

Prove that (sec A+1)/(tan A)=(tan A)/(sec A-1)

(1)/(sec A-tan A)=sec A+tan A

(1)/(sec A-tan A)=sec A+tan A

(sec A+tan A-1)(sec A-tan A+1)=2tan A
