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:
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

quadratic function in the link
