" 5.If tan "A=2" ,evaluate "Sec A sin A+tan^(2)A-cosec A" ."

If tan A=2, evaluate sec A sin A+tan^(2)A-cos ecA

If sin A= 1/3 evaluate cos A cosec A + tan A sec A

If sin A = 1/3 evaluate the cos A cosec A + tan A sec A.

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

If csc A=2, find the value of (1)/(tan A)+(sin A)/(1+cos A)

From the following figure, find the values of : (i) cos A (ii) cosec A (iii) tan^(2)A - sec^(2)A (iv) sin C (v) sec C (vi) cot^(2) C - (1)/(sin^(2)C)

Prove the following identities : (1 + (sec A - tan A)^(2))/(cosec A (sec A - tan A)) = 2 tan A

Prove that : (sec A - cosec A ) (1 + tan A + cot A)= tan A sec A-cot A cosec A .

(1 + cot A — cosec A) (1 + tan A + sec A) = 2 .

(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 ?
