please do the first 3 problems for symbolic logic first four implication rules only MP MT DS HS s Use the fi ollowing symbolized arguments. The number of lines provided below the arguments may be a tew more than you need to complete the proof,it just makes it easier for me to read st four implication rules andy (that is, MP, MT, DS, and HS) to derive the condlusions of the 3 point proofs: #2· 1.pvQ 3.

Use rules #1-8 to provide logical proofs with line-by-line justifications for the following arguments. (Note: you can use any of the rules that you wish; however, it is possible to solve the arguments in this section by using only the first 8 rules.) 1 1. E > (A & C) 2. A > (F & E) 3. E /F 2 1. (L v T) > (B & G) 2. L & (K = R) /L & B 3 1. (X...
Use Fitch to construct formal proofs for the following arguments. In two cases, you may find yourself re-proving an instance of the law of Excluded Middle, PV¬P, in order to complete your proof. If you've forgotten how to do that, look back at your solution to Exercise 6.33 in Language Proof and Logic 2nd Edition. Alternatively, with the permission of your instructor, you may use TAUT Con to justify an instance of Excluded Middle. (P->Q)<->(¬PVQ)
Show that the following is a valid argument. 1. y V t 2. (w V u) ^(w V x) 3. (q V r) rightarrow w 4. s V p 5. (y ^r) rightarrow x 6. (p ^q) rightarrow (t V r)
Directions. Determine whether the following three arguments are valid using the truth table method. Use the Indirect Truth Table method as found in the link on Canvas. Indicate whether each is valid or not. Note that ‘//’ is used as the conclusion indicator and ‘/’ is used to separate the premises. [Note: Use only the following logical symbols: ‘&’ for conjunctions, ‘v’ for disjunctions, ‘->’ for conditionals, ‘<->’ for biconditionals, ‘~’ for negations.] Show your truth tables. 1. (S <->...
