Sliders

Any time you have free variables in an expression, the calculator will offer to let you define them with sliders. You will see the option to add sliders appear in the expression bar once you finish typing in your equation. 

You can also use the same variables in several expressions to plot curves that will change together. 

In this example, the value of c defines two parallel lines that move up and down together.

In this example, the two lines stay perpendicular to each other for any value of m.

To adjust the limits and interval of your slider, click either of the values at the ends of the slider bar. Input your values and click "set to complete the adjustment.

 

Try the sliders tour in the help menu to try creating sliders in the calculator:

    How to change a slider to a fixed constant?

    if you have variable a which equals 2, and you want to get rid of play button, just change it from a=2 to a=2+0x. That is basically tricking it because it has x in the equation, even though x does nothing.

    Is there a way to create a table given the slider values and show the slider values in the equation?  I'd love to have students see how the equation changes when the values for the variables change too :)

    Is there a way to move the points from right to left? Now, the only options are from left to right and "back and forth". How can I move the slide from right to left?

    It would be useful to be able to advance the slider one unit to the left or right using the keyboard (not just the mouse, which can be inaccurate).

    For later reference: this can be done by clicking on the slider cell, then clicking "tab" twice, then using the arrow keys.
