Understanding Points in Set Notation

• When dealing with unique solutions, it is essential to properly represent them in set notation.

Notation for Unique Solution

• Set Containing One Point:

  • Use parentheses for points, not vectors.

  • Example of a point in set notation: (a, b)

Curly Bracket Notation

• If using set builder notation (optional in this context):

  • Representing the point in curly brackets:

    • For a unique solution point:

      • Correct Form: { (a, b) }

Key Points

• Always use parentheses

• Use curly brackets only for a set containing one point.
