This document provides instructions for using various features of the Desmos graphing calculator, including how to draw quick graphs by typing functions, add sliders to graphs containing variables to explore different values, plot points, view tables of a function's values, and change graph settings like axes. Key features covered are drawing graphs, using sliders, plotting points, viewing tables, and modifying graph settings.
Learning to use the Desmos Graphing Calculator
- 2. Desmos Graphing Calculator Follow the instructions here to create Desmos graphs. Learn about: 1. Drawing a quick graph 2. Plotting Points 3. Sliders 4. Points of interest 5. Tables 6. Settings
- 3. Desmos Graphing Calculator Note that many slides have hyperlinks which will take you direct to a Desmos page you can experiment with. Sometimes hyperlinks will be in the main body of the slide. Hyperlinks to graphs will be in this position
- 4. Draw a quick graph Suppose you want a graph of y = 3x+2 Simply go to Desmos and type in your function That’s it – one graph! y = 3x+2
- 5. Learn about sliders Now suppose you want to explore straight line graphs. Simply go to Desmos and type in your function but this time use variables: You will be offered the chance to add sliders – select all
- 6. Learn about sliders y = mx+c Now you have sliders Try changing them and watch that graph!
- 7. Learn about sliders If you want a slider to have integer values only, select one of the end points: then you could make the step size 1 for integer values and also change the lowest and highest values if you want y = mx+c try changing the sliders
- 8. Learn about sliders If you want a slider to have integer values only, select one of the end points: then you could make the step size 1 for integer values and also change the lowest and highest values if you want y=mx+c, m and c integers
- 9. Plot some points Plot some points
- 10. Graph a function x f(x) = x + 3
- 11. Points of Interest Points of interest
- 12. Tables First enter your function then select edit list and choose convert to table
- 13. Tables y = 1/x with table
- 14. Tables y = 1/x with table Now try changing the table: Change the first value of x Delete the other rows Enter a second value of x ....then keep pressing enter
- 15. Tables y = 1/x with table – more values
- 16. Settings Try changing the x and y axes Try changing the axes for the quadratic function in the link below Quadratic - try changing axes
