(1-sin A)/(1-sec A)-(1+sin A)/(1+sec A)=2cot A(cos A-cosec A)

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

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

Prove that (sec A-1)/(sec A+1)=((sin A)/(1+cos A))^(2)=(cot A-cos ecA)^(2)

(1+tan A)/(sin A)+(1+cot A)/(cos A)=2(sec A+cosec 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)

(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 ?

sin A(1+tan A)+cos A(1+cot A)=sec A+cosec A

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

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

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