सिद्ध कीजिए कि -
` (sin 2A)/( 1+cos 2A) = tan A.`

(c) (sin A)/(1+cos A)=tan(A/2)

Prove: ( sin 2 A)/( 1 + cos 2 A)= tan A

Prove that (sin2A)/(1+cos2A)=tan A

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

(1 + sin2A-cos2A) / (1 + sin2A + cos2A) = tan A

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

Prove that (sin A+sin 2A)/(1+cos A +cos 2A)=tan A

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

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

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