Exploration of roots as the inverse of exponents. Includes description of how the laws of roots mirror the laws of exponents, since expressions involving roots can be rewritten as expressions with rational exponents.
Explanation of logarithms: what are they, when are they useful, in what ways can logarithmic expressions be rewritten (laws of logarithms), and descriptions of the most common situations in which they are likely to be encountered or needed.
A few more interactive GeoGebra applets have been added to my collection. Each of these graphs the function indicated in the name, with parameters that you can adjust using sliders. As you move a slider, you can watch how that parameter affects the graph of the function, and see what the resulting function definition looks…… Continue reading Interactive Graphs for Exponential and Logarithmic Functions
Descriptions of life skills (skills useful in daily and business life) learned in elementary through high school mathematics courses.
