Prove that: sin 3x + sin2x – sin x = 4 sin x cos x/2 cos 3x/2. Solving LHS sin 3x + sin 2x − sin x = sin 3x + (sin 2x – sin x) cos3x=sin2x+cosx cos3x=sin2x+cosx: cos3x=sin2x+cosx. 1 lip 20:34. Adamm: cos(2x)cosx−sinxsin(2x)=sin(2x)+cos(x) (cos(2x)−1)cosx=sin(2x)(1+sinx) ... Apr 3, 2015 ... So you have sin2x=cos3x sin ⁡ 2 x = cos ⁡ 3 x , so sin2x=sin(π2−3x) sin ⁡ 2 x = sin ⁡ ( π 2 − 3 x ) , so π2−3x=2x π 2 − 3 x = 2 x , π2=5x π 2 = ... Nov 16, 2023 ...
