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 and direction of the resultant are found. Resolving vectors into their components is also explored. The ordered pair for any vector can be found with the sine and cosine ratios. The final two programs apply vector principles to the real world through the concept of force. 6-part series, 10 minutes each.
