You are given the parametric equations x=2cos(θ),y=sin(2θ).x=2cos⁡(θ),y=si n⁡(2θ). (a) list all of the points (x, y)(x, y) where the tangent line is horizontal. in entering your answer, list the points starting with the smallest value of xx. if two or more points share the same value of xx, list those points starting with the smallest value of yy. if any blanks are unused, type an upper-case "n" in them.

Question: what is the value of x 4x-2= (-7) +5x. it would be greatly appreciated if someone could actually explain to me step by step
