Discussion Overview

The discussion revolves around finding the Cartesian equation for the perpendicular bisector of the line segment connecting points A (2,3) and B (0,6). It includes mathematical reasoning and clarification of terms related to the concept of bisectors.

Discussion Character

  • Homework-related, Mathematical reasoning, Conceptual clarification

Main Points Raised

  • One participant requests assistance in deriving the equation for the perpendicular bisector, expressing difficulty with the problem.
  • Another participant suggests breaking the problem into subproblems, including finding the midpoint, determining the direction vector of the line segment, identifying a normal vector, and constructing the perpendicular line.
  • A participant questions the meaning of "bi-sector," indicating a lack of understanding of the term.
  • Subsequent replies clarify that a "bi-sector" refers to a line that bisects the segment, passing through its midpoint.
  • Further clarification is provided on the etymology of "bisect," explaining that "bi" means two and "sect" means cut, thus defining bisect as "cut in two."

Areas of Agreement / Disagreement

The discussion does not reach a consensus on the solution to the problem, as participants focus on clarifying terms and breaking down the problem rather than providing a definitive answer.

Contextual Notes

Participants have not yet addressed specific mathematical steps or assumptions required to derive the equation for the perpendicular bisector, leaving some aspects of the problem unresolved.

Find a cartesian equation for the perpendicular bisector of the line joining:
A, (2,3) and B, (0,6).

Haven't come across this before, and really am stuck!

Thanks in advance.

Split your problem in several subproblems:
1. What is the coordinates of the midpoint of the line segment?
2. Which unit vector is parallell to the line segment ? (That is, determine the direction vector to the line segment!)
3. Which unit vector is normal to the line segment's direction vector?
4. Construct the perpendicular by using the facts:
a) The perpendicular goes through the midpoint
b) Is parallell to the normal vector

I'm not so good on maths! What is a bi-sector?
 
"bi-sector" bisects the line,i.e. goes through the midpoint of the line.
 
"bi" means two, and "sect" means cut. so bisect is "cut in two".
