Troubleshooting Calculator Issues: Wolfram & Equation in Photo

Click For Summary

Discussion Overview

The discussion revolves around troubleshooting issues with a calculator, specifically Wolfram Alpha, in relation to solving a differential equation presented in a photo. Participants explore the structure of the equation and its components, focusing on its formulation and potential simplifications.

Discussion Character

  • Technical explanation, Homework-related, Debate/contested

Main Points Raised

  • One participant expresses confusion about why Wolfram Alpha does not provide a result for their equation and suggests simplification might be necessary.
  • Another participant questions whether the term y'' is indeed multiplying y' in the equation.
  • There is a suggestion that the equation might be miswritten and proposes an alternative form: y'' + 6y' + 8y = 16t^2.
  • A participant confirms they have the equation as originally stated and considers the possibility of an error in their homework list, indicating they may need to consult their teacher.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correct formulation of the equation, with some proposing alternative interpretations while others maintain their original version. The discussion remains unresolved regarding the exact nature of the equation.

Contextual Notes

There are indications of potential misunderstandings regarding the notation used in the equation, as well as uncertainty about the classification of the problems on the homework list.

TL;DR
differential equation
I have the problem with checking solution in calculators. For example wolfram doesn't give result of this equation. Have you any idea what is going on? Maybe should I simplyfy something. The equation is placed in photo.

Is y'' really multiplying y'?
 
Yes, I have it on my homework list.
 
Surely that would have been written as 6y''y' not y'' \times 6y'?

Are the other problems on your homework list second order linear ODEs?

Are you sure it isn't y'' + 6y' + 8y = 16t^2?

I am sure it is like I have written. Perhaps it is mistake in my homework list, so I need to contact with my teacher. Thanks for help.
