Curated OER
Sin, Cos and Tangent
Students find the identity o sine, cosine and tangent. In this precalculus lesson plan, students solve and identify the different parts of a right triangle. They use the ratios of the Pythagorean Theorem to find the missing side or angle.
Curated OER
Law of Sine and Cosine
Learners solve problems using the law of sine and cosine. In this precaclulus lesson plan, students learn the law of DeMoivre's Theorem and Heron's theorem. They use both theorems to solve problems.
Curated OER
More of DeMoivre's Theorem
Students identify DeMoivre's Theorem. In this precalculus lesson, students derive the law of sine and cosine as it relates to DeMoivre's Theorem. They identify the best time to use these formulas.
Curated OER
Law of Sines Word Problems
Young scholars solve word problems using the law of sines. In this precalculus lesson, students work in groups as they define vocabulary terms. They apply the formula of sine to answer and solve problems.
Curated OER
Law of Sines
Students solve problems using sine and cosine. In this precalculus lesson, students ask questions about the Law of sines and its application to the real world. They derive the correct formula of sine for each problem.
Curated OER
Law of Cosines Word Problem
Students solve problems using the law of cosines. In this precalculus activity, students meet different criteria as they solve problems. They apply the formula for cosines to solve word problems.

The Number System
Review complex numbers, real numbers, irrational and rational numbers, integers, and whole numbers with math students. Use this guide as a reference sheet or handout.
Curated OER
Domain of a Function
In this precalculus instructional activity, students examine and determine the domain of the three functions provided and apply them to the three problems.
