This shows that the graph Therefore, it suffices to let is symmetric about the change between 0 and If e is then r is 0. Next, we compute the values of r for increasing values of 0. If 0 is then r is approximately Similarly, if 0 is then r is then r is approximately In the Also if e is case of 0=T/2 we have r=4 because is zero. If 0 is we have r is Also, if 0=5T/6 then r is approximately Finally, r is when 0 is Tt.
