Unformatted text preview: Math 20C Calculus Practice Midterm II February 17, 2006 Name: Lecture Hour: Section Hour: Guidelines for the test: • No books, notes, or calculators are allowed. • You may leave answers in symbolic form, like √ 42, unless they simplify further, like √ 9 = 3 ,e = 1, or cos(3 π/ 4) =- √ 2 / 2. • Use the space provided. If necessary, write “see other side” and continue working on the back of the same sheet. • Circle your final answers when relevant. • Show all steps in your solutions and make your reasoning clear. Answers with no explanation will receive no credit, even if they are correct. • You have 50 minutes.
