Learning to use the Desmos Graphing Calculator

Tutorial - using the Desmos Graphing Calulator

1. Desmos Graphing Calculator Examples Colleen Young

2. Desmos Graphing Calculator Follow the instructions here to create Desmos graphs Learn about: Drawing a quick graph Sliders Points of interest Tables 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. Points of Interest Points of interest

10. Tables First enter your function then select edit list and choose convert to table

11. Tables y = 1/x with table

12. 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

13. Tables y = 1/x with table – more values

14. Settings Try changing the x and y axes Uncheck Equalize Axis Scales for more control over the axis settings Experiment with the three show settings to see what happens Try changing the axes for the quadratic function in the link below Quadratic - try changing axes
