" 2.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 tan a=2/sqrt13 , then the value of (cosec^2 a+2sec^2 a)/(cosec^2 a-3 sec^2 a) is : यदि tan a=2/sqrt13 ,है, तो (cosec^2 a+2sec^2 a)/(cosec^2 a-3 sec^2 a) का मान:

If tan alpha=2 , then the value of (cosec^2 alpha-sec^2 alpha)/(cosec^2 alpha+sec^2 alpha) is यदि tan alpha=2 है, तो (cosec^2 alpha-sec^2 alpha)/(cosec^2 alpha+sec^2 alpha) का मान ज्ञात करें।

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

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