Finding dy/dx, dy/dt, dx/dt in plot mode.

[Shacvet]

Greetings, I am former Ti-Calculator user and I am having one issue with the HP Prime calculator. I am unable, in plot mode (graphing) to find dy/dt, dx/dt, dy/dx like I can with the Ti-84 and up calculators. I know that I can find a Tangent line in Function mode (but you are not able to select a specific point) but I can not find out how in other modes (Apps). On the Ti calculators, it has a Calc function to find all the Tangent lines, max/mins and values. This is extremely usful on the Ti when doing implicit.  Does this exist on the HP Prime?

Hi!, @Shacvet:

You can with App Advanced Graphing, see ...

Can you indicate, if this is your question ? ... https://youtu.be/xTofCWXtYyU

In the Function app you can select a specific point on the graph by pressing: menu - Go To.

You can show the tangent and slope by pressing: Fcn.

The Advanced Graphing app can plot very complicated relations between x and y.

It can show intersections and horizontal and vertical extrema by pressing in Plot view:

Menu - Trace - PoI - eg Horizontal Extrema.

You can do the same thing in its Numeric view and it will give you lists.

The Geometry app is less good than the Advanced Graphing app in plotting relations between x ands y but it can show tangent lines, also through a point which is not on the graph.

You can do this with the instruction: tangent, in its Symbolic view.
