If sin4x a+bcos2x+ccos4x then a b c
WebSimilarly, since b b divides c c, b c b∣c, there exists an integer n n such that c=bn c = bn (Equation #2). Now, substitute the expression of b b from Equation #1 into the b b in Equation #2. By doing so, the equation c=bm c = bm is transformed to c= (am)n c = (am)n. Websin 4 x + cos 4 x = 1 - 2sin²xcos²x = 1 – 1/2 .sin 2 2x Thay vào phương trình ta có: 1 – 1/2 .sin 2 2x+ 1/2.sin2x= 0 => 2 – sin 2 2x + sin2x = 0 => sin2x = 2 (loại) hoặc sin2x = -1 (thỏa mãn) Với sin2x = -1 => 2x = => x = Kết luận phương trình có một họ nghiệm.
