# Drawing of the parabola f(x,y) in the GEOMETRY application

07-18-2019 02:59 AM

Hi.

I would like to report a problem with drawing parabol f(x,y) in the GEOMETERY application. I don't know why the application draws parables of different lengths (shorter and longer). On the attached screenshots of HP PRIME calculator you can see it exactly. The big problem is that the parabola drawn by the calculator has short arms e.g. y^2 = 4*x. It is not possible to make different geometric and analytical analyses, etc. A similar problem occurs when we construct a parabola manually having a given point and a line. However, this application does not have any problems with drawing parabol f(x) , e.g. x^2+3x or similar. Advanced Graphing application does not have such problems. It draws all possible super parabols. And I want GEOMETRY to draw every parable as well.

Dear Mike,

I have HP PRIME G1 , Firmware version 2.1.14181 (2018 10 16). And I have such a simple question . Does HP PRIME G2 draw in a similar way to G1 or already correctly. I am very interested in it. Someone can check it out and share this information on this forum. Thank you and greetings!

Thank you for your answer. There is not enough data on the new G2 calculator. I have one more question. I have a virtual calculator G1 from Firmware 2.1.14181 in my computer. And if there is a virtual calculator HP PRIME G2. I am waiting for your answer.

Bast regards,

Thank you for sending me the material that describes

HP PRIME G1 calculator . Date of creation of this material : 2013. Very good introduction for beginners of this calculator. But whether something similar exists for the latest HP PRIME G2 calculator.

Hello, everyone.

I have a request to those who own the latest HP PRIME G2 calculator. Attached here are the screenshots of my G1 calculator with two parabolas. Can anyone draw these parables on G2 and upload screenshots. I would like to compare them. Thank you very much.
