This online graphing calculator helps visualize and compare graphs and equations.
Just type in the equations into the side bar and the graph will appear as you type.
To change colour of the graph, go to Settings and then select the graph you would like to edit.
Clicking on the graph will allow you to choose it’s colour.
There is a built in keyboard with all of the functions you can use, so just find the one you need and put it into the sidebar.
For this demo slam, we incorporated a variety of functions to create a snowman.
It was a fun, simple way to demonstrate how to use this web tool for new users.
The equations we used are:
Function of a circle: (x – h)2 – (y – k)2 = r2
- h represents the horizontal shift
- k represents the vertical shift
- r represents the radius of the circle
Function of a line: y = mx + b
- m represents the slope
- b represents the y-intercept
We also used the slider function on Desmos to animate the snow falling.
The slider function allows users to set a loop on a variable within an equation.
We used the variable i in the circle function:
(x – h)2 – (y – i)2 = r2
Now the circle will continuously shift down by a value of i.
Users can change the speed and direction of the loop by changing the settings of the slider.
For our falling snow, the slider was set at 0.5x speed and the loop would begin from -1000 and run to 1000.
