WebSolve 1 + 2 sin x = 2 for 0 ≤ x ≤ 360 2 sin x = 1 sin x = 0.5 From example 1, x = 30 0 There are two values for x that satisfy the equation; they are 30 0 and 150 0 x = 30 or x = 150. … WebSolve 3cosx +sin x =2 for 0°≤x≤360°. Solution Method 1 Note that cos2 x and sin2 x are very simply linked using cos 2 x +sin2 x =1 so a 'rearranging and squaring' approach would seem in order. Rearranging: 3cosx =2 −sin x Squaring: 9cos 2 x =4 −4sin x +sin2 x ⇒ 91()−sin2 x =4−4sin x +sin2 x ⇒ 0 =10sin 2 x −4sin x −5 trulia affoedable homes https://annitaglam.com
