सिद्ध कीजिए कि `(sec A - tan A)^(2) ( 1 + sin A) = 1 - sin A`

( sec A + tan A ) ( 1 - sin A ) = ?

Prove that (sec A-tan A)^(2)(1+sin A)=1-sin A

(sec A+ tan A) (1 - sin A) equals to

Prove: (sec A-tan A)^(2)=(1-sin A)/(1+sin A)

Evaluate (sec A + tan A) (1- sin A) for A = 60^(@) .

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

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