(1 point) cos(x)tan(x)+cos(x)=0 find all angles in radians that satisfy the equation. for each solution enter first the angle solution in [0,π) or [0,2π) (depending on the trigonometric function) then the period. when 2 or more solutions are available enter them in increasing order of the angles. (e. g. x=π/2+2kπ or x=3π/2+kπ etc.) note: you are not allowed to use decimals in your answer. use pi for π.
