Giải bởi Vietjack. Ta có : cos2 x + sin x + 1 = 0. ⇔ ⇔ 1 - sin2x + sin x + 1 = 0. ⇔ ⇔ - sin2x + sin x + 2 = 0. ⇔ ⇔ sin2x - sin x - 2 = 0. ⇔ [sinx = −1 sinx = 2 (V N) ⇔ [ sin x = − 1 sin x = 2 ( V N) ⇔
Hence, we need both cos 2 x = 0 and sin x + 1 = 0. In other words, we need cos x = 0 and sin x = − 1. A quick look at a sine and cosine graph will show you that x = 270 ∘ is one possibility. In fact,
As you suggest, since cos 2 x = cos 2 x − sin 2 x, this is equivalent to the equation cos 2 x = 1, which has solutions when 2 x is an integer multiple of 2 π, so the solutions are x = …, − 2 π, − π, 0

No you may not. If you'd like to divide by 2, you must divide both terms on the LHS by 2. Not just your 2cos(2x) term. If you divided both terms by two, you'd be left with cos(2x)+ 21 sin(x) = 41 ...
Calculus. Solve over the Interval cos (2x)+sin (x)=1 , [0,2pi) cos (2x) + sin(x) = 1 cos ( 2 x) + sin ( x) = 1 , [0,2π) [ 0, 2 π) Subtract 1 1 from both sides of the equation. cos(2x)+sin(x)−1 = 0 cos
