1. Precalculus – MAT 170 (Arizona State University)

This precalculus is part of ASU Universal Learner® Courses. This college-level course prepares you for calculus by focusing on quantitative reasoning and functions.

They expect students to set the skills to describe the behavior and properties of linear, exponential, logarithmic, polynomial, rational, and trigonometric functions.

After the course, students should be able to:

  1. Use introductory algebraic operations on numbers, expressions, and equations
  2. Apply algebraic and trigonometric reasoning to crack a range of problems
  3. Solve real-world application problems
  4. Begin future studies in calculus

The school provides individualized coaches as you move through each new subject and utilize the ALEKS learning system. It delivers students a personalized experience since they will be instructed on the topics they are most ready to learn.

Students may opt between a self-paced version or an instructor-led one in this course. In the first case, the course allows students to complete course assignments at their own pace, as long as they are completed within a year. But if you opt for an instructor-led, courses have a structure with a weekly assignment due dates and an instructor guiding a student through the curriculum and content. You must finish it within 16 weeks.

Here’s a sample video from the precalc course that gives some insight into teaching style/what to expect…

What Are The Most Important Things To Look For In An Online Precalculus Course?

Precalculus, for newcomers, can be confusing. But learning it online can be just as effective as taking a class in person.

To get the best out of an online course you’ll want to look for the following qualities:

  • Structure: how well are the course goals defined and the curriculum laid out?
  • Time commitment: does the course give you a rough estimate of how much time you’ll need to commit to it each week?
  • Cost: does it fit your budget?
  • Instruction: is the teaching professor suitably qualified and delivering the classes in an easy-to-understand format?
  • Prerequisites: what level of knowledge should you have before starting the course?
  • Support: once signed up, how much support is available to you to help meet your goals?
  • Assessment: how isyour knowledge and progress assessed?

Many of these questions are answered in the introductory table at the beginning of this article.

Anything else should be researched via your own criteria and the contact you make with course providers.

Good luck!

What Study Tips Can I Use For Precalculus?

Precalculus, like most other STEM subjects, is best studied by actively working through problem sets and building on your knowledge as you go.

Rote memorization can be done via an effective spaced-repetition system (we recommend Anki) but the real learning comes in applying that knowledge to exam-style practice problems.

The video below provides lots of useful tips on performing well in the subject…
