Cos 2x Cosx 2 0

Cos 2x Cosx 2 0 - Explanation: cos(2x) = 2cos2(x) − 1XXXX (This is one version of the double angle formula for cos) So. XXXXcos(2x) + cos(x) −2 = 0. can be written as. XXXX2cos2(x) +cos(x) − 3 = 0. This can be factored as: XXXX(2cos(x) +3)(cos(x) −1) = 0. So cos(x) = − 3 2 XXXX or XXXXcos(x) = 1.

Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step x=0, (2pi)/3, (4pi)/3 Recall that cos(2x)=cos^2x-sin^2x. Now, we have cos^2x-sin^2x-cosx=0 However, we want our equation in terms of only one trigonometric function. We can easily get everything in terms of cosine: sin^2x+cos^2x=1 sin^2x=1-cos^2x Thus, cos^2x-(1-cos^2x)-cosx=0 2cos^2x-cosx-1=0 This resembles a quadratic function, except it is composed of cosines. So, let's factor it as we ...
