I'm not sure where to start with these proofs. Any suggestions getting started would be appreciated.
1. Show that is A,B are linear operators on a complex vector space V, then their product (or composite) C := AB is also a linear operator on V.
2. Prove the following commutator relationships for Linear Operators A,B,C:
a. [A,B + C] = [A,B] + [A,C]
b. [A,B] = -[B,A]
c. [A,BC] = B[A,C] + [A,B]C
d. [AB,C] = A[B,C] + [A,C]B
