Movable Points

You can change a static point to a movable point by clicking and long holding the icon next to the expression list. A style editor will pop up with different drag options.

Another way to create a movable point is to enter a point with a parameter for one or both coordinates. Click and drag the point around the graph to change the value of the parameter(s).


To make graphs more interactive, use parameters from your movable point in your expressions.

    Is it possible to find the t value(s) for a certain point on a parametric curve? In particular, I'd like to find the two adjacent values for the single intersection on the Cayley sextic.

    This is obviously too late for you, but in case someone else also wants to move a picture along a function, here is one way you could solve the Angry BIrds problem.

    Here is a graph I made which makes it super duper easy to find the slope, distance, and line created by any two points:
