What Is Precalculus Math?
Precalculus is a series of courses designed to prepare students for calculus. It focuses on a number of topics, such as trigonometry, sets, inverse trigonometric functions, polynomial functions, exponential functions, and rational functions. Students are expected to understand the mathematical meaning of dynamic systems and to model real-world data. These skills are important for a variety of careers.

For many high school students, precalculus serves as a bridge to the more advanced mathematics that students will encounter in college. However, even students with a background in math have a steep learning curve. This can be especially true for those who are pursuing a career in science, technology, engineering, or mathematics. Fortunately, there are resources available that can help you get ready for precalculus, including an online course from Kahn Academy.
While the focus of precalculus is primarily on algebraic concepts, some courses also cover logarithmic and rational functions. Students will explore these functions in both verbal and numerical forms. In addition, a common topic in precalculus is the binomial theorem.
Depending on the career path of the student, a variety of courses will be offered. The structure of the course will vary, but the overall goal is the same: to prepare students for calculus. Most students are required to take at least one precalculus course before taking a calculus course. Whether they are enrolled in a traditional precalculus class or an online course, students will be challenged to use the techniques they’ve learned in other math classes to solve problems.
Precalculus can be used to fulfill a math requirement for a variety of colleges. Even students who do not intend to pursue a STEM major should consider taking at least a third or fourth year of math. If you are considering a math-based career, however, you should consider if the course will prepare you for the advanced level of math that you need to succeed.
Students who are interested in precalculus should first consult their college’s math department. Some schools offer a diagnostic test to determine what they need to know before taking a precalculus course. Those who are not eligible for a diagnostic test may be able to earn credit for the fourth year of math if they complete a formal precalculus course.
Before taking a precalculus course, students should make sure they are comfortable with trigonometry. Trigonometry is a prerequisite for most calculus courses, and a good understanding of the subject is critical to success.
Although precalculus is not required for students who wish to take AP Calculus AB, it is recommended. Taking an AP course can strengthen the foundation for college-level math courses, such as introductory statistics or physics. AP students will have access to the AP Classroom, which includes personalized feedback reports, instructional videos, and formative assessments. A variety of AP programs also provide scholarships to qualified teachers.
The AP Precalculus assessment test is also designed to prepare students for calculus. It contains 29 questions, and is designed to assess how well a student understands the content of precalculus. Unlike other tests, it is not intended to be an official class placement.
