The polar coordinates of two points are P1 = (2.8 m, π/6 rad) and P2 = (4.2 m, 2π/3 rad). (The diagram is not specific to this problem, but simply illustrates the relationship between Cartesian and polar coordinates.) Express your answers to this problem in units of meters.
Part (a) What is the x coordinate of point P1?
Part (b) What is the y coordinate of point P1?
Part (c) What is the x coordinate of point P2?
Part (d) What is the y coordinate of point P2?
Part (e) What is the distance between the points?
