" 8.Prove that ":(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: (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) = 2 cosec A

Prove that (tan A)/(sec A-1)+(tan A)/(sec A+1)=2 cosec A .

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

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

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