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

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

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

tan((pi)/(4)-(A)/(2))=sec A-tan A=sqrt((1-sin A)/(1+sin A)A)

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

Prove: (1-cos^2 A)cdot sec^2B + tan^2B (1-sin^2A) = sin^2A+tan^2B .

(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 A)/ (cos A)

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

tan (45 ^ (@) + (A) / (2)) = sqrt ((1 + sin A) / (1-sin A)) = sec A + tan 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)
