  • Instructions

    Precalculus (Metric Version), 10th edition, written by Ron Larson and published by Cengage Learning, is known for sound, consistently structured explanations of mathematical concepts and exercises to expertly prepare students for calculus. In this edition, the author continues to revolutionize the way students learn by incorporating more real-world applications and innovative technology. The WebAssign component for this title engages students with many features, and links to a complete eBook.

    Question 1 grades all solutions written as a list. The prompt alerts the student to enter a comma-separated list of answers.

    Question 2 contains expression grading where any equivalent form of the expression is accepted. Also included are a Master It tutorial, Watch It, and solution.

    Question 3 enforces that the answer is written as a complex number and includes a Watch It.

    Question 4 demonstrates grading for factored expressions in the first answer blank. Also included are a Master It tutorial, Watch It, and solution.

    Question 5 highlights grading used for an expanded logarithm per the question instructions.

    Question 6 is a multi-part question which shows one of many prompts used to indicate to the student what to enter when there is no answer.

    Question 7 requires the evaluations of the the sine, cosine, and tangent of the angle to be entered in simplest form.

    Question 8 exhibits an expandable matrix answer blank that grades the matrix as a whole, and also handles answers for matrices that cannot be computed. Also included are a Master It tutorial, Watch It, and solution. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.

    The answer key and solutions will display after the first submission for demonstration purposes. Instructors can configure these to display after the due date or after a specified number of submissions.
