Our fully accredited Common Core-aligned Integrated Math III course builds upon the strong foundations formed in Integrated Math I and Integrated Math II, further developing students' knowledge and skills in polynomials, rationals, radicals, exponentials, logarithms, number systems, geometry, trigonometry and probability. Upon successful completion of this course, students will have attained the necessary knowledge and skills needed to be successful in Precalculus.

As part of this comprehensive course, students generalize their knowledge of quadratics to higher-order polynomials. This includes factoring polynomials using various methods, solving polynomial equations, and dividing polynomials. Students will also grasp fundamental polynomial theorems such as the factor and remainder theorems, learn how to plot polynomials and describe their properties.

Students will learn to solve both exponential and logarithmic equations and further develop their aptitude for modeling scenarios with exponential functions, such as calculating compound interest. Additionally, they will develop fluency in radical, rational expressions and equations, including manipulating and simplifying expressions, solving equations, and plotting graphs.

Building upon the foundations laid in Integrated Math II, students will strengthen their knowledge of sequences to include arithmetic and geometric sequences. They'll also explore properties of the real number system, and use their knowledge of quadratics as a stepping stone to investigate the fascinating world of complex numbers.

Students deepen their knowledge of geometry to include circles and parabolas in the coordinate plane. They will further develop their understanding of trigonometry to include the law of sines and cosines, graphs and properties of trigonometric functions.
