Hi one of my questions is the following:
sketch the graph of the function h : [1, 3] belonging to Real Numbers where:
h(t):= [(n+1)Sigma(j=1)] g(tj)x [tj, t{j-1}](t)
and x[tj, t{j-1}] is the characteristic function of the half open interval [tj, t{j-1})
Is there an easier way to explain all of this?
