Websin^2 (x)=1/4, so you know sin (x) = 1/2 or -1/2. Solve sin (x)=1/2 and sin (x)=-1/2 for the range, and then remember to make x pheta (as I couldn't be bothered to put a pheta sign … 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

WebApr 16, 2024 · sin^2 (x) = 1. sinx =+ or - sqr1 = + or -1. x = 90 or 270 degrees. cosx = 0. x= 90 or 270 degrees. Answer: x = 90 or 270 degrees or pi/2, or 3pi/2 radians. If you don't recognize how to get from cosx=0 to x=90, and 270, draw a unit circle, the more vertical the angle, the closer to 90 or 270, the smaller cosx is, until it reaches zero. or punch ...
