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
Draw a quick graphSuppose you want a graph of y = 3x+2Simply go to Desmos and type in your function
That’s it – one graph!
y = 3x+2
Learn about slidersNow 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
Learn about sliders
y = mx+c
Now you have sliders
Try changing them and watch that graph!
Learn about slidersIf 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
Learn about slidersIf 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
Tables
First enter your function
then select edit list
and choose convert to table
Tables
y = 1/x with table
Now try changing the table:Change the first value of xDelete the other rowsEnter a second value of x
....then keep pressing enter
SettingsTry 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 thequadratic function in the link belowQuadratic - try changing axes
