यदि `cos A+ cos ^(2)A=1` हो, तो `sin ^(2)A+ sin ^(4)A=`

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

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

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

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

If (cos ^ (4) x) / (cos ^ (2) y) + (sin ^ (4) x) / (sin ^ (2) y) = 1 then prove that (cos ^ (4) y) / (cos ^ (2) x) + (sin ^ (4) y) / (sin ^ (2) x) = 1

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-

If sin A+sin^(2)A=1, then show that cos^(2)A+cos^(4)A=1

Prove that: (cos 2A cos 3A -cos 2A cos 7A + cos A cos 10A)/("sin" 4A sin 3A - sin 2A sin 5A + sin 4A sin 7A) = cot 6A cot 5A

Prove that: (cos 2A cos 3A-cos 2A cos 7A + cos A cos 10A)/(sin 4A sin 3A -sin 2A sin 5A + sin 4A sin 7A)= cot 6A cot 5A .
