Check out the handout from a presentation that contains a collection of high school algebra projects connecting a variety of mathematics to the real world. Activities range from simple probabilities to calculus. The activities...

Students investigate trigonometry.  In this Algebra II/Pre-calculus/Trigonometry instructional activity, students explore Islamic achievements in mathematics as they calculate angles and distances using the Law of Sines and the Law...

For this Pre-calculus/Trigonometry worksheet, students use the laws of sines and cosines to solve triangles. The four page worksheet contains thirteen problems. Answers are not included.

Students define the law of cosine and its correct usage. In this trigonometry lesson, students define the law of Heron's area formula and use it to solve problems. They review other trigonometric values and identify the identities.

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.
