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 cosA+cos^(2)A=1 , then prove that sin^(2)A+sin^(4)A=1 .

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

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

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

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

If (cos^(4)A)/(cos^(2)B)+(sin^(4)A)/(sin^(2)B)=1 then prove that (i)sin^(2)A+sin^(2)B=2sin^(2)A sin^(2)B(ii)(cos^(4)B)/(cos^(2)A)+(sin^(4)B)/(sin^(2)A)=1

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

((1) / (sec ^ (2) A-cos ^ (2) A) + (1) / (cos ec ^ (2) A-sin ^ (2) A)) sin ^ (2) A cos ^ (2) A = (1-sin ^ (2) A cos ^ (2) A) / (2 + sin ^ (2) A cos ^ (2) A)

If (cos^(4)A)/(cos^(2)B)+(sin^(4)A)/(sin^(2)B)=1, Prove that: sin^(4)A+sin^(4)B=2sin^(2)A sin^(2)B
