Mathematics Describing the Real World: Precalculus and Trigonometry

GPS Devices and Looking Forward to Calculus (1x36)

:

In a final application, locate a position on the surface of the earth with a two-dimensional version of GPS technology. Then close by finding the tangent line to a parabola, thereby solving a problem in differential calculus and witnessing how precalculus paves the way for the next big mathematical adventure.
