Solve for x cos(2x)+cos(x)=0, Mathway
If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. 2cos(x) 1 = 0 2 cos (x) 1 = 0 cos(x)+1 = 0 cos (x) + 1 = 0 Set the first factor equal to 0 0 and solve.
How do you find exact solutions of cos2x cosx = 0 in the
cos2x (1 cos2x) cosx = 0 2cos2x cosx 1 = 0 This resembles a quadratic function, except it is composed of cosines. So, let''s factor it as we would any quadratic function.
