Product Description
The Algebra Applications series brings real-world, relevant applications of algebra to today s classroom. This series also integrates technology through the use of the Texas Instruments TI-Nspire graphing calculator. The key features of this series include: Guided applications that are interdisciplinary and can be done as an in-class group activity. All keystrokes are clearly shown. Dynamic footage and animations bring math to life. Math concepts are developed clearly, making this series an ideal supplement to an Algebra 1 or Algebra 2 class. The ten titles in the series include: Algebra Applications: Functions and Relations In this episode of Algebra Applications a simulated future journey to Mars offers a way of exploring conic sections, and their underlying functions. Students use the Graphs and Geometry features of the TI-Nspire. Parabolic paths. The liftoff and pre-orbital 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. 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. Elliptical paths. The planets orbiting the sun follow elliptical paths. In fact, the trajectory of a spacecraft traveling to Mars would also be elliptical. Students explore these various ellipses.
