Your work must be legible, and the organization must be clear. You must show all your work, including correct vector notation. Correct answers without adequate explanation will be counted wrong. Incorrect work or explanations mixed in with correct work will be counted wrong. Cross out anything you don’t want us to read! Make explanations complete but brief. Do not write a lot of prose.
