    Another optimization problem

    Motion on a line:
    the position of two particles on the s-axis are s1 = sint and s2 = sin (t+pie/3), with s1 and s2 in meters and t in seconds

    a) At what time(s) in the interval 0 <= t <= 2 pie do the particles meet?
    b) what is the farthest apart that the particles ever get?
    c) when in the interval o <= t <= 2 pie is the distance between the particles changing the fastest

    a) would I set s1= s2 ? and then set everything to zero? and after that I am kind of lost

    b) what I did so far is just go s1 - s2 and then take the derivative....... but don't know what to do after that

    c) I don't know how to start this portion
