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

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

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

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.
