These programs illustrate trigonometric functions in a clear and dynamic format that makes full use of the advantages of computer animation. Methods of solving right-angled triangles, using the sine, cosine, and tangent ratios, are presented. The sine and cosine laws are then developed, and several examples involving oblique triangles are introduced and solved. The series ends with the application of the sine and cosine laws to some real-world situations. 6-part series, 10 minutes each.

		Conic Sections This series investigates the properties of the figures known as conic sections. A cone is intersected with a plane at different angles. An examination of the graphs of some simple second-degree relations reveals the shape of the parabola. The equatio...(more details)		VHS $299.70 DVD $299.70
		Quadratics This series of six programs uses vivid computer animation to introduce quadratic equations and their corresponding functions on the Cartesian plane. With different coefficients, several quadratic equations are solved and graphed on the plane and comp...(more details)		VHS $299.70 DVD $299.70
		Trigonometric Functions 2: Sinusoidal Waves Sine, cosine, and tangent functions are introduced through an examination of their graphs on the Cartesian plane. To develop a general equation for sinusoidal waves, the characteristics of amplitude and period are examined. The program shows that the...(more details)		VHS $299.70 DVD $299.70
		Linear Systems With dynamic animation, this six-part series explores several techniques for solving linear systems. The series begins with the method of solving one linear equation with one variable. This is accomplished when the value of the variable that will mak...(more details)		VHS $299.70 DVD $299.70
		Vectors Using computer animation, this series investigates vectors. The definition of a vector is developed with several examples. Vectors at right angles to each other are added, and by means of the Pythagorean theorem and the tangent ratio, the magnitude a...(more details)		VHS $299.70 DVD $299.70
