Q:

# What is precalculus?

A:

Precalculus is a course that prepares students for calculus classes. Advanced ability with functions, analytic geometry, function representations, algebraic expressions and a familiarity with trigonometry are all part of the scope and sequence for precalculus, according to The College Board.

## Keep Learning

Precalculus students learn the general properties of functions, their notation and how to perform symbolic function operations, and they learn to treat functions as models. Representing functions graphically, symbolically and in tabular form is another important skill in precalculus. Expanding existing knowledge of algebraic expressions and equations to include radical, exponential, trigonometric and logarithmic examples is another element of the course.
