Sliders

Overview

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.

    I like that the play button moves the sliders forward and backward.   And, I like that you can click the --> <--- button to change it to ---> --->  (above one another) so that the slider only plays forward.   But, I make a lot of physics models.  My most common slider is for time.   I wish there was a way for it to simply play once, and not repeat.  (Is there?)
