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=

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)

cos^(4)A-sin^(4)A is equal to 2cos^(2)A+1(b)2cos^(2)A-1(c)2sin^(2)A-1( d) 2sin^(2)A+1

cos^4A-sin^4A is equal to (a) 2cos^2A+1 (b) 2cos^2A-1 (c) 2sin^2A-1 (d) 2sin^2A+1

Prove that cos^(4)A-sin^(4)A=cos^(2)A-sin^(2)A .

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