# Question: When the x s are equally spaced the calculation of

When the x’s are equally spaced, the calculation of and can be simplified by coding the x’s by assigning them the values . . . ,- 3,- 2,- 1, 0, 1, 2, 3, . . . when n is odd, or the values . . . ,- 5,- 3,- 1, 1, 3, 5, . . . when n is even. Show that with this coding the formulas for and become
