(1 point) List all angles in radians that satisfy the equation 2cos(x)sin(x)−2‾√cos(x)=0. Each item in the list should be an expression of the form θ+kω where 0≤θ<2π, and ω is the smallest positive period of the function f(x)=2cos(x)sin(x)−2‾√cos(x), and k=⋯,−2,−1,0,1,2,⋯ ranges over the integers. Separate items by commas. Note: You are not allowed to use decimals in your answers.
