Regular Homework Guidelines

In order to get credit for regular homework assignments, you must follow the following guidelines. Your submission must be completely legible, on standard letter-size paper. Your submission must be stapled into one packet.

Each starred problem must be on its own page, with no other problems above or below, even if you use multiple pages to solve the problem. Solutions to starred problems must be formulated in theorem-proof form. You will have to reformulate the problem in the form of a theorem in order to do this. Keep in mind that problems are often formulated as questions or instructions (prove that, show that) but theorems are just statements of fact, they don't instruct you to do anything.

For example, a plausible theorem statement matching §1.3#15 is:

Theorem. The set of all differentiable real-valued functions defined on \(\mathbb{R}\) form a subspace of \(\mathsf{C}(\mathbb{R})\).

If a problem has multiple parts, you may need to have more than one theorem for your solution.
Non-starred problems can be gathered together on the same page but leave enough room for the grader to make notes.

You must restate each problem before you solve it. You are encouraged to restate the problem in your own words. For example, a good way to start a solution to §1.2#11 is:

I will show that the set \(\mathsf{V} = \{0\}\) that consists of the single vector \(0\) with \(0 + 0 = 0\) and \(c0 = 0\) for every scalar \(c\) in \(F\) is a vector space.

Make sure all problems are appropriately labeled.
