In this episode of Algebra Applications, two real-world explorations of inequalities are developed. Hybrid Cars. An examination of the equations and inequalities that involve miles per gallon (mpg) for city and highway traffic reveals important information about hybrid cars and those with gasoline-powered engines. Floods in Venice. Venice experiences a great deal of flooding, and with the expected rise of sea levels over the next century, this ancient city is in peril. Through a series of inequalities, students analyze the impact of flooding.

Applications of Equations and Inequalities
VIDEO: Algebra Nspirations: Inequalities VIDEO: Algebra Nspirations: Inequalities VIDEO: Algebra Nspirations: Inequalities

Used in just about any industry, inequalities, like equations, are fundamental building blocks of algebra. Written and hosted by internationally acclaimed mathematics educator Dr. Monica Neagoy, this video explores inequalities--concepts, properties, solutions, and notations--connects them to real-world contexts, and uses the TI-Nspire to make the algebra meaningful. The focus of this program is on linear inequalities in one and two variables. Concepts explored: Equations, inequalities.

Topic

Triangles

Description

This animation illustrates the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. The animation visually demonstrates this principle, helping students to understand and apply it in geometric contexts.

Animated math clip art provides a clear and engaging way to learn complex concepts. Teachers can use this animation to explain the Triangle Inequality Theorem and its applications in geometry.
