Please help me with this one. I'm really struggling with it. Thanks.

1. Get examples of:
o a theorem with a direct proof, and
o a theorem with an indirect proof.
The proofs should be short and simple.
You may use proofs that are already
published in literature or online references.
Make sure you indicate the references.

2. For each proof, examine the following and
highlight the specific sections in the proof.
You may also give brief descriptions or
explanations.
• At which part of the proof are the
premises used?
Simply highlight in the proof the section
where the premises are used.
• Which valid argument forms are used in
the proof?
The proof might contain several valid
argument forms. It is enough to specify
ONE valid argument form in the proof.
• What results other than those in the
premises are used in the proof?
Several "a priori" mathematical results
might have been used in the proof. It is
enough to specify ONE such prior result in
the proof. You may also indicate ONE prior
mathematical concept that have been used
but is not indicate in the premises.
