(b) Prove that the composition of the derivatives d²/dx², d³/dx³: P4 → P4 is the zero map despite that neither map is the zero map. (c) Give matrix equations representing each of the prior two items. When two things multiply to give zero despite that neither is zero, each is said to be a zero divisor. Prove that no zero divisor is invertible.
