Proof Project Writing Assignment Using the "road map" provided during class for the example theorem, prove the theorem "If n is odd, then n+1 is even" in the following ways: 1) Direct proof (Assume p, show q ). 2) Proof by contraposition (Assume ~q, show ~p). 3) Proof by contradiction (Assume p and ~ q, then seek a contradiction). It is important to consider your audience when doing any type of writing. For this assignment, assume you are writing your proofs so that another student in the class who has missed a few lessons can follow your logic and easily understand your proofs. As you read through your proofs, consider the following questions: ● Does each proof align with the traditional proof structure discussed in class? ● Do the ideas flow clearly and logically from one sentence to the next? ● Is there any missing information that would contribute to the clarity of the argument (consider the audience when thinking about this)? ● Is the proof general enough to…
