Additional Resources

• Office Hours: Your instructor wants you to be successful in your precalculus course. Please reach out as soon as possible if you have questions about the material covered during class.  This semester's office hour schedule can be found in the course syllabus, which is posted on your course Blackboard Learn page. Feel free to ask for help from any precalculus instructor, even if they are not the instructor who teaches your class section.

• OpSTEM Drop-In Study Center: Located in RT1401, the OpSTEM Drop-In provides a quiet work space to collaborate with classmates and STEM Peer Teachers (SPTs). 

• Math Learning Center: Located in BH230, the MLC provides free, drop-in peer tutoring for a wide variety of math classes.

• Academic Support Hub: Located in BH233, the Hub provides support for general study skills and your other STEM classes.

Textbooks: available for free online. You can look in the table of contents of any book to find the topic we are currently working on. Practice problems will be found at the end of each section, with additional review problems at the end of each chapter. Many textbooks will provide answers at the back of the book for odd-numbered exercises.

• OpenStax Precalculus, 2nd ed. 

• Apex Pre-Calculus

Complete courses: available online for self-directed study

• MyOpenMath: Sign up for a free student account by clicking HERE. After you sign in, click the button that says "Enroll in a New Class." From the drop down menu, select "141 Precalculus 1 (College Algebra) Self-Study." If you want to see a preview of Precalculus II, you can also enroll in "142 Precalculus 2 (Trig) Self-Study".

• CEMC Courseware at the University of Waterloo: In Precalculus I at CSU, approximately the first 5 modules of this CEMC course are covered.

• Khan Academy: This is a popular website for review, video explanations, and extra practice. There is no single course in Khan Academy that covers exactly the content covered in Precalculus I at CSU, so I suggest that you use the search bar on the site to find resources for the particular topic you want to practice.

YouTube Channels: search these channels for solved examples of particular problem types. Warning: It is fine to use online resources, including YouTube, to help you review or practice with a concept. However, do not fall under the misconception that you have learned to do math by watching someone else solve problems. On your tests and quizzes, you will need to be able to solve problems independently, so you need to have done enough independent practice to feel confident with each topic and problem type.

• Mathispower4u: Use the search bar to find examples relevant to the topic you are working on. 

• Scalar Learning: This youtube channel features full video solutions to every odd-number problem in the OpenStax Precalculus textbook, organized by chapter and section. 

• Professor Leonard: This is a complete Precalculus I & II course, taught live by Professor Brandon Leonard and recorded. Note that the content of these videos does not align exactly with the content taught in Precalculus I & II at CSU, but you can look for videos relevant to a specific topic we have covered in class.

• The Organic Chemistry Tutor: As the name suggests, this channel includes videos about chemistry, but it also has many instructional videos about math. Again, you should use the search bar to find videos relevant to what we are covering in class.
