How vày you solve sin (x/2) + cosx -1= 0 over the interval 0 lớn 2pi? | Socratic

0, 2pi, pi/3; 5pi/3 -->interval (0, 2pi) Use trig identity: cos 2a = 1 - 2sin^2 a cos x = 1 - 2sin^2 (x/2). Gọi sin (x/2) = t, we get: t + (1 - 2t^2) - 1 = t(1 - 2t) = 0 2 solutions: a. T = sin (x/2) = 0 --> x/2 = 0 --> x = 0, and x/2 = pi...
