11 Desmos Challenges: Sliders (#4)

Turn your beautiful graphs into dynamic explorations packed with opportunities for noticing and wondering by adding sliders.

Basic

Goal: Use three expression lines to create a movable point.

4.1 Prompt

Note: Movable points are points that are movable. Oh, wait. You already got that, didn’t you? (Well, I was the last person on the planet to understand why it’s called a Pizookie.)

Advanced

Goal: Use five expression lines to graph a quadratic function (in vertex form) with a movable point for its vertex.

4.2 Prompt

Note: Movable points are cool. Movable points linked to other objects are amazing!

Legendary

Goal: Use five expression lines to plot the parent sine function, a movable point on the sine function, and the line tangent to the curve at that movable point. In other words, a tangent line roller coaster!

4.3 Prompt

Bonus: Instead of defining the derivative on your own, ask Desmos to do it. You may find d/dx useful…

Note: Get rid of extra distractions by turning off the graph of the derivative. (A little click on the circle in the expression list will do the trick.)
