WebJun 1, 2015 · 2 sin ( x) + 1 = 0. sin ( x) = − 1 2. x = 7 π 6 + 2 π n, 11 π 6 + 2 π n. sin ( x) + cos ( x) − 1 = 0 which answered in my yesterday post cos x + sin x = 1. and get x = 2 n π, 2 n π + π 2. Combine all the solutions, x = 2 π n, x = 7 π 6 + 2 π n, x = 2 π n + π 2, x = 11 π 6 + 2 π n. trigonometry. Share.

WebHint: sin(2x) = 2sinxcosx so your equation becomes : 2sinxcosx+cosx = 0 cosx(2sinx +1) = 0. If 41 is a solution of sin2x = pcosx , then p is? (a) -3 (b) 0 (c) 1 (d) -1 I think option (b) is correct, but I want solution. p = 0.4948 Explanation: sin2x = pcosx ⇔ 2sinxcosx = pcosx or cosx(2sinx− p) = 0 ... WebFor f(x)=sin(2x),g(x)=cosx a.
