Rovers in Calculus

[Ellen Browne]

Hi All,

I recently demoed the rover to a math department and the calculus teacher wanted some ideas on using rovers in her class. Suggestions welcome! 

Thanks

If they are doing AP Calculus BC, doing polar graphs is really fun to do with the rover.

 

Euler's method (Hidden Figures scene not really ancient) is also essentially how the rovor can be programmed to move: Turn an angle move delta x, get new slope, move delta x.

The speed is the derivative of position. Most anything with motion connects to calculus and the rover moves :)

Hi Kim

 

Thanks for sharing the idea about plotting the polar curves with TI-Rover

 

 

> I am finding that the analyzing data from the motion detector is applicable to calc for many applications at both the AB and BC level. unfortunately my rovers tend to be used after school for math club more than in the classroom.

I also really like the idea of using the motion detector data.

 

Is there anything we (TI) can do to make it easier to use the TI-Rover in the classroom (as opposed to in the math club)?

More sample activities? More “getting started” documents?

 

Thanks,

- Harshal

I have had my students plot polar curves using the rovers in the past. The students really loved the activity. Now that polar is a part of AP Precal, I would move that activity to AP Preacl. I am finding that the analyzing data from the motion

Yes, I think that Sample activities for the rover for the various mathematics (and science) classes would be a boon for its increased use.

Here is the program I use for the TI-Rover to draw polar graphs.

I’ve found for math teachers keeping it “math forward” is helpful. 

The program was simple and interactive/troubleshooting. For example, when you first press CTRL R in the program and then press enter, the program first asks if you turned the Rover on.

Enjoy,
