Precalculus Series

Precalculus is a continuation of previous foundations from Algebra 1, Geometry, and Algebra 2. Students use functions, equations, and limits to express generalizations and to analyze and understand a broad variety of mathematical relationships. The Applications in Precalculus Series uses functions to represent not only algebraic and geometric situations, but those involving probability, statistics and trigonometry, as well as calculus.

## Precalculus

• ### The Robotic Arm

Precalculus
Students will study the movement and mechanics of the robotic arm on the ISS using their knowledge in geometry and precalculus.

• ### Simulating Weightlessness

Precalculus
Students will study the flight pattern of NASA’s C-9 jet using their knowledge of precalculus and parametric equations.

• ### Space Vectors

Precalculus
Students will use spherical coordinates and vector addition to find position coordinates of the space shuttle with respect to the Earth’s center.

• ### Rendezvous for Two

Precalculus
Students will describe the circular orbits of the space shuttle and the International Space Station (ISS) and predict the trajectory of the space shuttle as it rendezvous’ with the ISS.

• ### Earth Can You Hear Me Now?

Precalculus
Students will investigate, analyze and model the communication time lag between Earth and Mars.

• ### The Lunar Lander - Ascending from the Moon

Geometry, Algebra 2, Precalculus
Students will apply trigonometric functions when using data from the liftoff of the Lunar Lander from the Moon's surface.

• ### Communications and the Lunar Outpost

Geometry, Algebra 2, Precalculus
Students will apply mathematics formulas to calculate various geometric measures in the relationships between the height of a lunar communication tower and the tower’s communications range.
