" 2."(sec A+tan A)(1-sin A)=cos A

(sec A+tan A)(1-sin A)=sec A(b)sin A(c)cos ecA(d)cos A

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

(sec A (sec A + tan A)(1-sin A))/ ((cosec^2 A-1)sin^2 A) is equal to: (sec A (sec A + tan A)(1-sin A))/ ((cosec^2 A-1)sin^2 A) का मान क्या होगा ?

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

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

Prove the trigonometric identities: (1+cot A+tan A)(sin A-cos A)=(sec A)/(cos ec^(2)A)-(cos ecA)/(sec^(2)A)=sin A tan A-cot A cos A

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

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

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

Show that (i) sin^(8)A-cos^(8)A=(sin^(2)A-cos^(2)A)(1-2sin^(2)A.cos^(2)A) (ii) (1)/(sec A-tan A)-(1)/(cos A)=(1)/(cos A)-(1)/(sec A + tan A)
