Sample Problems

Problems related to Precalculus, Fourth Edition (Blitzer)

The value of reviewing these sample problems and solutions is twofold. The more obvious benefit relates to problems that a student has difficulty solving themselves; a solution is provided. Less obvious is the set of techniques used in our solutions; some of the techniques used on the sample problems may not be taught in the classroom. We concentrate on efficient solutions and shortcuts; so a review of the solved problems may present new techniques that enable a student to be more efficient in their approach to solving problems.

Semester Review (Blitzer Chapters 4 to 6)


Students of Trigonometry may find the following to be useful references.

PC Apps

There is no specific Geometry App, but when the student begins to study basic Trigonometry, the Trigonometry App may be of interest.

TrigStar Sample Tests

The TrigStar Program Contest is an annual high school mathematics competition sponsored by the National Society of Professional Surveyors. You can visit their website here. National and local awards are provided for contest winners.

A formula sheet for use on the exams, as well as a number of practice tests, are provided below.
