VIDEO: Algebra Applications: Functions and Relations 
VIDEO: Algebra Applications: Functions and RelationsIn this episode of Algebra Applications, students explore the following scenario: Scientists use conic sections to map the trajectories of spacecraft in flight. The setting for this episode is a planned future flight to Mars. 

VIDEO: Algebra Applications: Functions and Relations, 1 
VIDEO: Algebra Applications: Functions and Relations, Segment 1: Introduction.Scientists use conic sections to map the trajectories of spacecraft in flight. The setting for this episode is a planned future flight to Mars. As the ship travels from Earth to Mars, parabolic, circular, and elliptical paths are explored.

VIDEO: Algebra Applications: Functions and Relations, Segment 2: Parabolic Paths.The liftoff and preorbital path of the rock is described by a parabola. Students explore the properties of parabolas from the standpoint of the parametric equations that describe the horizontal and vertical directions of motion for the rocket.

VIDEO: Algebra Applications: Functions and Relations, Segment 3: Circular Paths.The path of a rocket orbiting the Earth can be modeled with the equation of a circle. Students explore the quadratic relation and the parametric equations that can be used to model the path of a spacecraft orbiting Earth.

VIDEO: Geometry Applications: Circles 
VIDEO: Geometry Applications: CirclesIn this program we explore the properties of circles. We do this in the context of two realworld applications. In the first, we look at the design of the Roman Coliseum and explore how circular shapes could have been used to design this elliptical structure. 

VIDEO: Geometry Applications: Circles, 1 
VIDEO: Geometry Applications: Circles, Segment 1: The Basics of Circles.We visit Chaco Canyon in New Mexico to explore the circular kivas and in the process discover how circular buildings have been used to study the heavens. 

VIDEO: Geometry Applications: Circles, 2 
VIDEO: Geometry Applications: Circles, Segment 2: Circles and Arcs.The Roman Coliseum is a large elliptical structure. Yet, the Romans likely used circular arcs to build it. This segment explores the properties of circles and shows how arcs can be used to create elliptical shapes. 

VIDEO: Geometry Applications: Circles, 3 
VIDEO: Geometry Applications: Circles, Segment 3: Chords and Inscribed AnglesThe Roman Pantheon is a domed structure that shows a keen awareness of the position of the sun throughout the year. The source of light from the top of the dome allows for the exploration of chords, inscribed angles, central angles, and intercepted arcs.
