An assignment in CS 303. Some problems are from MCS

Assignment

  1. Prove an identity.
    1. Give a proof that the subseteq operator makes a partial order. Namely, prove that the subseteq operator is reflexive, antisymmetric, and transitive. When you need to use names for sets, use A, B, C in the proof. PROOF.
    2. Give a proof that set intersection is associative. When you need to use names for sets, use A, B, C in the proof. PROOF.
  2. Basic questions about sets / basic reasoning / using the identities and rules for sets.
    1. MCS Problem 15.4. What is the answer, you should come up with a formula, and explain why.
    2. MCS Problem 15.5. Make sure to only use set notation in part a. In part b, give a formula, also work it out, and explain.
    3. MCS Problem 15.9. Again, give formulas, explain why, work them out. ** most interesting problem.
    4. MCS Problem 15.13. Again, give formulas, explain why, work them out.
    5. MCS Problem 15.30. ** tied for most interesting. PROOF.
    6. MCS Problem 15.35. What is the answer for each, and explain why.
