## What do I need to know for precalculus?

The first step toward determining if you need a precalculus course is to determine what you want to study. If you are pursuing a career in engineering, medicine, or another math-related field, precalculus may be necessary to prepare you for your future college courses. However, if you are looking to study business, then taking precalculus in high school probably won’t be as beneficial as a similar course in college, and it could even be harder to understand than in college. Precalculus is a course that is usually taken in 11th grade to prepare students for the next math course, calculus, which typically takes place in 12th grade. It combines trigonometry with math analysis and is typically taken by students who have already completed algebra and geometry.

It can feel like you are trying to drink from a firehose, especially if this is your first time taking a precalculus course. But if you take your time and work hard on the concepts, you can do well in this class and prepare yourself for college-level calculus.

### What are the topics of a standard precalculus course?

Typical precalculus courses include several algebraic and trigonometric topics that can be helpful for a wide range of math-related careers. They cover topics such as conic sections, Euclidean vectors, and other areas of math that are essential for understanding calculus. Some of these topics are also important in other fields, such as business or engineering.

Functions are the most common concept in precalculus, and knowing what they are and how they work is essential for success. The type of functions you need to know will vary based on the specific course, but some of the more common ones are linear, quadratic, absolute value, square root, polynomial, exponential, logarithmic, and trigonometric.

Math formulas are equations that can be used to solve problems quickly and easily. These formulas often refer to basic mathematical concepts and can help you remember what a particular function means when it is being used in a problem.

They can also help you understand how a particular equation works, as they tell you what the values of each variable are, and which measure or input is needed to complete the equation. These formulas are a great reference when you’re studying for an exam or test.

You might find it useful to take an online diagnostic test that tests your knowledge of Algebra 1 and 2. This will help you figure out what areas of the course you need to focus on, and what kinds of material you should be reviewing before you start the class.

It can be difficult to decide whether or not you need a precalculus course, so it is important to check with your math department at the university or college you are considering. They can provide you with information about what to expect in the classroom, what materials you might need, and if you need any special equipment or accommodations to be successful in the course.
