rremark on plotting from a paedagogical point of view
The Prime ist an amazing graphing machine - definitely the best I have seen among its competitors on the market. Exploring functions is a joy using a touch screen.
As a math teacher I want to add a point to the wish list: At the moment the calculator puts numbers at the edges of the plotting window indicating the maximum and the minumum values - I would prefer to bind the numbers to the last tick mark on the axis. Reading off the values would be simplified. For more precise values one can go with the Trace feature. But students should learn to read a graph without the help of a cursor! Perhaps one could make the feature switchable (a flag)? |

RE: rremark on plotting from a paedagogical point of view
Yeah, I agree. Basically, the behavior is just left over from smaller screened devices with less resolution. That is on the list of enhancements/changes for future consideration.
I suspect it will automatically place the numbers at specific intervals appropriate to what you have zoomed at and use shading for major/minor grouping. e.g. Dark grey fror multiples of 10, light grey for multiples of 5 in between. TW Although I work for HP, the views and opinions I post here are my own. |

I didn't answer your question regarding pupils because, for those who speak and understand English, it doesn't require an answer: pupil and student mean the same thing, namely, those who attend schools. |

RE: rremark on plotting from a paedagogical point of view
Obviously there is different teaching content, too. My personal opinion is that it is worth being discussed if students need (or to be more precise: should use) a calculator like the prime at all if they fail at reading simple graphs...
But it is a totally different topic. I think everyone is aware that the students ThomasA has in mind are like 6th graders or so and not at a university level ;-) |

It's always nice to be informed so politely about a foreign language by a native speaker of it, since e.g. dict.cc translates 'pupil' as someone who attends schools while a 'student' may as well attend a university (a pupil doesn't). I learn something new about (American) English here every once and a while. d;-) |

Whenever you want to be sure what a word really means in American English, I suggest checking http://dictionary.com which is based on the excellent Random House Webster's Unabridged Dictionary. Check out their definition of "student" and notice that it's a synonym for "pupil". ![]() <0|ΙΈ|0> -Joe- |
