Principles of Macroeconomics 2e covers the scope and sequence of most introductory economics courses. The text includes many current examples, which are handled in a politically equitable way. The outcome is a balanced approach to the theory and application of economics concepts. The second edition has been thoroughly revised to increase clarity, update data and current event impacts, and incorporate the feedback from many reviewers and adopters. Changes made in Principles of Macroeconomics 2e are described in the preface and the transition guide to help instructors transition to the second edition. The first edition of Principles of Macroeconomics by OpenStax is available in web view here.

Program a progress bar for a presentation using basic coding. Time to complete: 45-90 minutes

Interactive multiple-choice assessment in which a graph is given and the properties of the graph must be observed. Such properties include zeros of the function, positive and negative intervals of the function, and monotonically increasing and decreasing intervals.

Purplemath gives several examples which clearly show the process of completing the square to find the maximum and minimum solutions to a quadratic equation.

An in-depth lesson which teaches you how to graph exponential equations. Examples are worked through step by step and explained in detail for different exponential equations.

Watch as the organ function grinder from the National Museum of Mathematics represents a quadratic function in a variety of ways. This video focuses on converting a verbal expression into an algebraic representation.

Richland Community College gives a definition and examples of a function. Also includes steps to evaluate piecewise functions on a calculator.

This lesson gives brief description of dependent and independent variables and how they relate to the exponential and logarithmic functions.

Examine how a giant sculpture at the National Museum of Mathematics represents the solutions to the equation y=x^2. This video focuses on the basics of graphing quadratic functions and the relationship between x and y values along the parabola.

The domain of a function is all the possible values of x's of ordered pairs; whereas the range of a function is all the possible values of y's of ordered pairs. You can easily find them by graphing the functions or ordered pairs. Let's see how in this lesson. Includes a video tutorial, examples, and practice problems.

Playing the role of engineers in collaborations with the marketing and production teams in a chocolate factory, students design a container for a jumbo chocolate bar. The projects constraints mean the container has to be a regular trapezoidal prism. The design has to optimize the material used to construct the container; that is, students have to find the dimensions of the container with the maximum volume possible. After students come up with their design, teams present a final version of the product that includes creative branding and presentation. The problem-solving portion of this project requires students to find a mathematical process to express the multiple variables in the prism’s volume formula as a single variable cubic polynomial function. Students then use technology to determine the value for which this function has a maximum and, with this value, find the prism’s optimal dimensions.

In this lesson the concept of a T-chart is explained. It is 1 of 5 in the series titled "T Chart." The video tutorial is accompanied by a short multiple-choice quiz. [2:25]
