" (i) "(1+sec A+tan A)(1-cosec A+cot A)=2

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

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

(1+tan A+sec A)(1+cot 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 ?

(tan A+cot A)=(sec A*csc A)

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

The value of the expression (1 +sec22^@ + cot 68^@)(1- cosec22^@+ tan68^@) is (1 +sec22^@ + cot 68^@)(1- cosec22^@+ tan68^@) व्यंजक का मान बताइए?

(cosec A - sin A)^2 + (sec A - cos A)^2 - (cot A - tan A)^2 is equal to
