Helpful Resources

  • Free Online Graphing Calculators – These calculators can be used instead of a graphing calculator for this course. (It is recommended that college-bound students get a graphing calculator, however, so they are already familiar with using one.)
    • Desmos (suggested, due to ease of identifying values and zooming in and out) – Note that you have to press the keyboard symbol in the bottom left to get a keyboard. Press y = and the values y equals, using x to stand for the independent variable. Use ^ to show exponents (use your right arrow to get back from an exponent to a regular value). Click on the graph of the curve itself to see the value at any particular point. Zoom in or out using the plus or minus signs. Add a second equation by clicking underneath where the first is typed and typing another one.
    • Math Is Fun – Use ^ to show exponents; use the first line for inputting the first equation, and the second for the second.

Corrections/Clarifications

Chapter 4, Lesson 6, Problem 46

The image shows how AB was found using the Pythagorean theorem. The other measurements were obtained the same way.
