  • Instructions

    College Trigonometry 1/e by Carl Stitz and Jeff Zeager, is an open source text available from Orange Grove Content Repository. Many questions are multi-part to demonstrate individual mathematical concepts needed to solve the problems. Click here for a list of all of the questions coded in WebAssign. 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 videos will ask you to create a login to the free resource, Brightstorm, part way through the video. The Brightstorm videos have been specifically chosen to support the concepts being presented in each linked question.

Assignment Submission

For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer.
