Given the recursive definition of Well-Formed Formulas (WFF):

  • Rule 1: Any single Latin letter is a WFF
  • Rule 2: if p is a WFF, then so are (p) and ¬p
  • Rule 3: if p and q are WFFs, then so is p→q
  • Rule 4: if p and q are WFFs, then so is p ∧q
  • Rule 5: if p and q are WFFs, then so is p ∨ q

Prove that ((p∧¬q)∨(r∧¬s)) →(¬r∧(¬w∨q)) is a WFF

Define a Q-sequence recursively as follows. B.   x, 4 − x is a Q-sequence for any real number x. R.   If x1, x2,   , xj and y1, y2,   , yk are Q-sequences, so is     x1 − 1, x2,   , xj, y1, y2,   , yk − 3. Use structural induction (i.e., induction on the recursive definition) to prove that the sum of the numbers in any Q-sequence is 4. Base Case: Any Q-sequence formed by the base case of the definition has sum x +...
