Use the Law of Cosines and the Law of Sines to solve problems using the sums of vectors. Pupils work on several different types of real-world problems that can be modeled using triangles with three known measurements. In the process,...

Students study the retreat of the Nez Perce Native Americans into Montana while tracing their journey on a map. They use the law of cosines to solve problems based on the navigational methods of the Nez Perce. They work with both the law...

Students graph trigonometric functions. In this precalculus lesson, students identify the properties of secant ,cosecant and cotangent. They use the unit circle as their formula to graph and analyze these functions.

Learners solve problems using the unit circle. In this precalculus instructional activity, students identify angles using the properties of the unit circle. They observe the trigonometric graphs and sine, cosine and tangent.

Students perform transformation on trig functions. In this precalculus lesson plan, students relate the London Eye observation wheel to trig function. They use a TI navigator to visualise the parameter created by this view and relate it...
