fe cos A + cos2 A =1 a fhoses ont for sin? A + sin4 A =1.

If cos A + cos^(2) A = 1 , then sin^(2) A + sin^(4) A is equal to

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

If cos A+cos^(2)A=1, find the value of sin^(2)A+sin^(4)A

Prove the following identities : (sin A + cos A)/ (sin A - cos A) + (sin A - cos A)/ (sin A + cos A) = (2)/ (2 sin^(2) A - 1)

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

If sin A + sin^2 A = 1 , then the value of cos^2A + cos^4 A is यदि sin A + sin^2 A = 1 , तो cos^2A + cos^4 A का मान है-

cos2a-cos2b + cos2c = 1-4sin a cos b sin c

if cos A+cos^(2)A=1 , then sin^(2)A+sin^(4)A=1

(sin A) / (1 + cos A) + (1 + cos A) / (sin A) = 2cos ecA

Prove that (1 + sin2A) / (cos2A) = (cos A + sin A) / (cos A-sin A)
