In this learning activity you'll evaluate the Sine, Cosine, and Tangent ratios of a right triangle.

In this interactive object, learners use the Law of Cosines to calculate forces.

In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this learning activity you'll evaluate the six trig functions using a scientific calculator.
