    Calculus help: find the points of inflection and discuss the concavity of the graph of the function?

    It appears that the graph of f(x) = 2csc(3x/2) in the domain (0, 2pi) is discontinuous at 2?/3 and 4?/3; these 2 points divide the domain into 3 same length intervals: (0, 2?/3), ( 2?/3, 4?/3), (4?/3, 2?) where the graph is respectively U ? U: concave up, concave down, concave up. the...
