Discussion Overview

The discussion revolves around a request for assistance with an example exam paper related to calculating the curl of a vector field, specifically in the context of a student with dyslexia seeking help. The scope includes homework-related queries and technical explanations regarding vector calculus.

Discussion Character

  • Homework-related
  • Technical explanation
  • Meta-discussion

Main Points Raised

  • Martyn seeks help for his grandson, who is dyslexic, with an example exam paper due to the unavailability of the lecturer.
  • Participants inquire about the specific type of help needed, indicating a willingness to assist.
  • There is a suggestion that the grandson may be trying to answer a specific question regarding the calculation of the curl of a vector field.
  • A participant notes that the question involves calculating ##\nabla \times \vec A## and references the formula needed for cylindrical coordinates.
  • There is a suggestion for the grandson to apply the formula and share his attempt for further assistance.
  • A moderator indicates that the forum cannot provide help via proxy and encourages the grandson to create his own account to seek help directly.

Areas of Agreement / Disagreement

Participants generally agree on the need for direct engagement from the student rather than assistance through a proxy. However, there is no consensus on how to proceed with the specific homework question due to the moderator's intervention.

Contextual Notes

The discussion is limited by the moderator's policy against proxy help, which may affect the flow of assistance and the ability to address the specific homework question directly.

The attached file shows several answers. What kind of help do you need?
 
Thanks, nothing seems attached?
 
The file you attached shows several answers.
 
Ah yes sorry.
He is dyslexic and finds it difficult to communicate.
Its good to know he can ask some questions and I will see what I can do.
Thanks again
Martyn
 
Thanks so much for your patience.
This is the paper Luke has given me.
His question is how to find the curl, If you can help I will pass it on to him.

Thanks

Purely a guess, but is Luke trying to answer Q1 (b) (i) in https://www.physicsforums.com/attac...ega_121_exam_2022_may_24-docxcurl-pdf.330446/ ?

Let’s assume this is the case.

The question says “Calculate ##\nabla \times \vec A##. Note that the symbols ##\nabla \times## mean ‘curl’ so the question is asking for the curl of vector ##\vec A##.

The value of ##\vec A## is stated (and is in cylindrical coordinates).

In the document below the questions, there is a “Formulae Sheet”. And below that there are some notes..

If you carefully read through the notes you will see it gives the formula needed to calculate ##\nabla \times \vec A## when ##\vec A## is given in cylindrical coordinates. Find the sentence starting “For a vector field ##\vec A## in cylindrical coordinates...”

Maybe Luke can apply the formula and you can post his attempt here for us to check.

Sorry @Martyn Arthur -- PF is not set up to provide schoolwork help via proxy. If your grandson would like our help, we are happy to help him just like all of the other students that we help. Please help him to sign up for a PF account, and coach him on how to use the PF and how to post in the schoolwork forums (showing his work on the solutions). Please also go through the LaTeX Guide link below the Edit window, so that he can post his math equations using LaTeX. Thank you; this thread will remain closed.
