Find, to the nearest tenth of a degree, all values of x in the interval 0≤x≤360 that satisfy the equation.
tan x=cos x
also solve for x in the interval 0≤x≤2π
cos ½x= cos x

Solve for x. (Let Sin x = k and solve using the quadratic formula.)
This is true where x is 0 and there also seems to be a solution between 45 and 60 degrees, as well as between 15 and 30 degrees. I suggest you draw an accurate graph to find the points.
