Explanation Given data: The given polar coordinate equation is written as follows: r 2 = 4 cos 2 θ Description: Condition for symmetric about the x -axis: If the point ( r , θ ) lies on a curve, then the point ( r , − θ ) or ( − r , π − θ ) also lies on the curve in order to satisfy the condition for symmetric about the x -axis. Condition for symmetric about the y -axis: If the point ( r , θ ) lies on a curve, then the point ( r , π − θ ) or ( − r , − θ ) also lies on the curve in order to satisfy the condition for symmetric about the y -axis. Condition for symmetric about the origin: If the point ( r , θ ) lies on a curve, then the point ( − r , θ ) or ( − r , θ + π ) also lies on the curve in order to satisfy the condition for symmetric about the origin. Rewrite the given polar coordinate equation as follows: r 2 = 4 cos 2 θ (1) Substitute ( r , θ ) in the Equation (1) as follows: r 2 = 4 cos 2 θ (2) Substitute ( r , − θ ) in the Equation (1) as follows: r 2 = 4 cos 2 ( − θ ) = 4 cos ( − 2 θ ) r 2 = 4 cos 2 θ { ∵ cos ( − θ ) = cos θ } (3) As expressions in Equation (2) and (3) are same, both the points ( r , θ ) and ( r , − θ ) lie on the given curve

Trolley of the overhead crane moves along the bridge rail. The trolley position is measured from the center of the bridge rail (x = 0) is given by x(t) = 0.5t^3-6t^2+19.5t-14 : 0 <= t <= 3 min. The trolley moves from point A to B in the forward direction, B to C in the reverse direction and C to D again in the forward direction.
