Reminder: All counting variables must be of INTEGER datatype.
Method 1: h = (b-a)/n x = a DO i = 2,n+1 x = x + h ENDDO Method 2: h = (b-a)/n DO i = 1,n+1 x = a + (i-1)*h ENDDOTest both methods using the values and n = 123456789. For both cases, compute the relative error in the value of x once the loop terminates (this should be equal to b). Which method is more accurate (i.e., which method has the smaller relative error)? Explain why the more accurate method has the lower relative error.
