    How to sketch H(sin(x)) if H(x) is a step function

    How would you start ?!

    Do you have a specific step function in mind? Over what interval are you trying to graph it?

    I think the simplest way would be to just divide the whole function up into n sub intervals that are the length of the step.

    that was a question on an old exam! nothing more.

    the step is assumed
    H(x) = 1 if x>0
    H(x) = 0 if x<0

    Use that definition to write what H(sin(x)) is. (Replace x by sin(x) everywhere in the definition).
