Discussion Overview

The discussion revolves around the meaning of a specific icon on the HP 50g calculator, described as a dot with two waves on each side. Participants explore its significance and implications for the device's functionality, as well as addressing a separate issue regarding the display of square roots and irrational numbers.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant inquires about the meaning of the icon, suggesting it may relate to IR emission.
  • Another participant humorously suggests that the icon indicates "Batteries empty!"
  • A different participant expresses frustration about not being able to display the square root of a vector in symbolic form, specifically seeking a solution to show it as a surd.
  • A subsequent reply provides a method to change the display settings to show future entries in symbolic form by using the RSHIFT key and pressing enter.

Areas of Agreement / Disagreement

The discussion includes a mix of inquiries and responses, with no consensus reached regarding the meaning of the icon. The issue of displaying square roots also remains unresolved, although a potential solution is offered.

Contextual Notes

The inquiry about the icon lacks definitive identification, and the solution for displaying square roots depends on specific settings that may vary among users.

Hello,

I have the HP 50g and I like it. Recently an icon has been light up on top and I don't know what it means. Its a dot with 2 waves on each side. It almost looks like an icon for some sort of IR emission.

Its in between the alpha and the hourglass. I haven't noticed it on before recently. What does it mean?

Batteries empty!
 
Oh ****! Thanks a lot!
 
I have the HP 50g. I can not get my answer in sq root ie absolute value of vector whose answer is sq root 10 shows the answer as a decimal. I have tried different mode settings with no luck. How can I get the answer displayed as a surd/irrational
thankyou
 
Push and hold down the RSHIFT key (the orange one), then press enter. You should see the tilde (~) turn into an equals mark (=). This will make it so that all of your future entries will be displayed in symbolic form.
