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

If A=30^(@) , show that : (1+sin2A+cos2A)/(sinA+cosA)=2cosA .

If A=30^(@) , show that : (1+sin2A+cos2A)/(sinA+cosA)=2cosA .

(1-cos2A+sin2A)/(1+cos2A+sin2A)=tanA

(sin2A)/(1+cos 2A) is

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

Prove that (1-cos2A+sin2A)/(1+cos2A+sin2A)=tanA

Prove the following : (1-cos2A+sin2A)/(1+cos2A+sin2A) = tanA

Prove that, (1+cosA+cos2A)/(sin A+sin2A)=cotA

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