Subtract sin 2 ( x) sin 2 ( x) from 2 sin 2 ( x) 2 sin 2 ( x). Apply pythagorean identity. = 2 sin(x) cos(x) - 2 cos(x) sin(x) = 0. Since the derivative is zero everywhere the function must be a constant. Take f(0) = sin^2(0) + cos^2(0) = 0 + 1 = 1. So. sin^2(x) + cos^2(x) = 1 everywhere.

Bạn giải phương trình bậc ba với nghiệm là $\sin2x$ là ra. b) Câu b tớ không rõ đề $\tan x - 3\cot3x = 2\tan x\Leftrightarrow \tan x=3\cot3x\Leftrightarrow \sin x\cos3x=3\sin3x\cos x\\\Leftrightarrow 2\sin3x\cos x+\sin(3x-x)=0\Leftrightarrow \sin2x(1+\cos2x)=0$ Nhớ tìm điều kiện của $\tan x$ và $\cot3x$
前面两个在误导你,cos2x+sin2x=cosx^2-sinx^2+2sinxcox=(cosx-sinx)^2,这明显不成立,就像 x^2-y^2+2xy=(x-y)^2是错误的一样。 过程,先提取根号2.
