Homework Help Overview

The original poster seeks assistance with rearranging variables in equations as part of a homework assignment. They mention specific equations, including E=mc^2, and express a desire to understand the procedure involved in isolating variables.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants encourage the original poster to share their attempts and identify specific points of confusion. Some suggest techniques such as completing the square and using inverse trigonometric functions to manipulate equations.

Discussion Status

The discussion is ongoing, with participants waiting for additional context from the original poster. Some guidance has been offered regarding potential methods for rearranging variables, but no consensus has been reached on specific approaches.

Contextual Notes

The original poster has not yet provided the equations in question, which may limit the depth of the discussion. There is also a mention of a document containing solutions, but its relevance to the current discussion is unclear.

Hello, the teacher gave us this assignment in which we had to separate some variables from equations. (example: E=mc^2 for m -> m=E/c^2). I had trouble with 4 of them (the ones in the attachment), I would appreciate some help, The procedure is really important since I want to learn how to solve them.

Hi woz,

While we're waiting for the attachment to get approved...

Why don't you go ahaid and post what you've tried / where you're stuck on them. It'll help us help you.
 
9. Do you know how to complete the square?

10. Can you get thins in terms of [itex]\cos \theta[/itex] and apply [itex]\arccos[/itex] to both sides?

11. Simmilar to 10

15. This seems to be a trick question, the equation isn't dependent on m at all :confused:
 
the solution in a word doc

regards
marlon
