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

If cosec theta = sqrt2 , find the value of : (1)/(tan A ) +( sin A)/(1+ cos A)

Prove that : (1+sin 2A)/(cos 2A) = (cos A + sin A)/(cos A - sin A) = tan (pi/4 + A)

Prove that (sin A)/(1 + cos A) + (sin A)/(1 - cos A) = 2 cosec 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 ?

(1 + sin2A) / (cos2A) = (cos A + sin A) / (cos A-sin A) = tan ((pi) / (4) +1)

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

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

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