PLEASE DO 1.9 b and e

1.9 The purpose of this exercise is to reinforce your understanding of the use of Leibniz (1.5) along with a hint in proving two expressions equal. For each of the following pair of expressions E[z := X) and Ez :=Y], identify a hint X = Y that would show them to be equal and indicate what E is.
