The pressure to take and excel in calculus in high school and college is undeniable. This branch of math is mostly seen as the pinnacle of school as it prepares students for careers in mathematics, engineering, sciences, economics, and computer science.

Top-tier colleges and universities also seem to prioritize gifted mathematics students. I’m sure you’ve heard of precalculus as a prerequisite for freshman-level calculus.

So, is precalculus necessary for calculus?

## Can precalculus get skipped in school?

Many students skip precalculus in school. It’s among the most skipped units in mathematics. However, should you skip precalculus?

There is high pressure to take precalculus in high school. Considering the application to top colleges is fierce, strong consideration is put on mathematics as a qualifying factor for top programs.

As such, excelling in math, including calculus, should be a priority. Gifted students who can master college-level calculus courses can skip taking precalculus.

However, precalculus can be extremely powerful and helpful if you fail to comfortably understand mathematical concepts of trigonometry, algebra, and logarithms.

Most students desiring careers in sciences and economics are required to grasp calculus concepts to qualify for these courses.

For instance, the standard prerequisite for college calculus is three years of high school mathematics. So if you haven’t developed a mastery of mathematics, it will require you to take a precalculus course.

You should only skip precalculus if you have mastered math or you have a plan after completing school.

Skipping can be detrimental to your understanding of mathematics as the material covered can leave you unprepared for a college degree.

**How important is precalculus to calculus?**

Precalculus is essential if you are preparing to advance into calculus. Precalculus is specially designed to prepare students for calculus.

The course introduces calculus concepts and serves as a building block to more challenging math courses. In precalculus, you are introduced to trigonometry, geometry, and algebra, the basics of calculus.

Calculus is a challenging math course that even bright students have trouble mastering. It is a difficult course to learn and comprehend; thus, precalculus is an easier route to lay the foundation blocks for calculus.

Concepts in mathematics build upon themselves. As such, beginner concepts from precalculus are pivotal to understanding more complex concepts in calculus.

In the precalculus course, take time to understand what is taught, as it will be essential later. The lessons may seem easy at first, but as they build on top of each other, the complexity increases, challenging your wit.

Keep pace to understand the basics of calculus; this knowledge will be required to excel in calculus.

**What math should I know before calculus?**

A solid calculus course demands mastery of several core areas in mathematics. These key areas include algebra, geometry, and trigonometry.

Every topic in math builds on previous topics, which is why it is imperative to comprehend these subjects. They serve as a prerequisite to mastering calculus.

Algebra is an important skill for understanding calculus. It deals with mathematical formulas and expressions that are essential to calculus.

Algebra is indispensable in solving problems in calculus, and you have to use algebra to solve calculus. The latter helps describe many complex processes, mostly using algebraic expressions.

Several fundamental concepts of algebra include fractions, powers, and logarithms. Skills in adding, multiplying, subtracting, and dividing fractions, dealing with negative powers, fractional powers, and distributions of powers are some prerequisites to understanding calculus.

Further, dealing with logarithms and solving quadratic equations will help you solve complex calculus problems.

The fundamental of trigonometry involves the sine, the cosine, and the tangent and their inverses which are the cosecant, the secant, and the cotangent.

Mastery of trigonometry allows you to solve for lengths and angles of sides and provides a host of other functions including the unit circle used to solve calculus problems.

Calculus also integrates with concepts of algebra. For instance, calculus can provide a more generalized approach to solving slopes and finding areas within a graph.

It helps to solve for shapes whose formulas lack geometry. Calculus also makes it easy to visualize graphs. However, you require basic geometry concepts to plot these graphs correctly.

These three topics are critical to mastering calculus. Trigonometry, algebra, and geometry are the building blocks of college calculus.

**Take Away**

Ultimately, taking high school precalculus isn’t necessary for college calculus. However, it does offer important concepts in algebra, geometry, and trigonometry.

Mathematics builds upon itself; topics learned earlier in the course are pivotal to mastering more complex concepts as you advance your studies.

So, it is important to equip yourself with these concepts taught in precalculus as they serve as the building blocks to mastering the more complex college calculus.
