High School Pre-Calculus Course

Time4Learning offers an online, interactive high school math curriculum that correlates to state standards. It can be used as a primary homeschool curriculum, a supplement to your current curriculum and as an afterschool or summer skill building program. At the high school level, Time4Learning is organized by courses rather than grade levels, so parents have the option of choosing any four as part of membership.

The pre-calculus curriculum is one of five math courses offered at the high school level. Pre-calculus is taught using practical, real-life math problems delivered by a combination of multimedia lessons, instructional videos, printable worksheets, quizzes, tests and both online and offline projects.

This page includes information about the material covered in the high school pre-calculus course.

  • Graph parabolas, circles, ellipses, and hyperbolas as conic sections, identify features of the graphs, and write the equations given a graph. They will also derive the equation of a hyperbola and an ellipse given the foci and a vertex, or the center, a focus, and a vertex.
  • Graph functions in polar coordinates, translate between rectangular and polar coordinates, and use De Moivre’s Theorem.
  • Graph functions in parametric form, translate between rectangular and parametric equations, and solve application problems by using parametric equations.

Chapter 7 – Linear Algebra and Matrices

The materials in this chapter introduce and cover Linear Algebra and Matrices. It is organized into sections that teach, reinforce and test students on how to perform matrix operations, find inverse matrices and determinants, and solve systems of equations by using matrix methods such as the Gauss- Jordan Method, inverse matrices, and Cramer’s Rule.

In this chapter, students will learn how to:

  • Perform the operations of addition, subtraction, and scalar multiplication on matrices. They will also define the inverse of a matrix and find inverses of 2 x 2 matrices.
  • Use geometric and algebraic methods such as matrix methods, including the Gauss- Jordan Method, inverse matrices, and Cramer’s Rule to solve systems of equations. They will interpret 2 x 2 and 3 x 3 systems of equations geometrically, and represent them using matrices that include dependent, independent, and inconsistent systems.
