if `sin x +sin^2 x = 1` then `cos^12 x+ 3 cos^10 x + 3 cos^8 x + cos ^6 x =`

If sinx + sin^(2)x =1 then cos^(12)2x + 3cos^(10)x+3cos^(8)x + cos^(6)x =

If sin x + sin^(2)x=1 then prove that cos^(12) x+3 cos^(10) x+ 3 cos^(8) x+ cos^(6) x=1 .

If sin x + sin^(2) x =1 " then " cos^(8) x + 2 cos^(6) x + cos^(4) x =

if sin x+sin^(2)x=1 then cos^(12)x+3cos^(10)x+3cos^(8)x+cos^(6)x=

If sinx + sin^(2) x = 1 , then the value of cos^(12)x +3 cos^(10) x + 3 cos^(8) x + cos^(6) x - 2 is equal to

If sin x+sin^2=1 , then cos^8 x+2 cos^6 x+cos^4 x=

If sin^(2)x+sin x=1 then cos^(12)x+3cos^(10)x+3cos^(8)x+cos^(6)x-1=

If sin x + sin ^(2)x =1, then the value of (cos ^(12) x+ 3 cos ^(10) x +3 cos ^(8) x+ cos ^(6)x) is-
