3rd degree polynomial is called a cubic

Click For Summary

Discussion Overview

The discussion centers around the terminology used for polynomials, specifically why a 2nd degree polynomial is referred to as "quadratic" despite the prefix "quad" suggesting four. The conversation touches on the origins of the term and its relation to geometric concepts.

Discussion Character

  • Conceptual clarification, Meta-discussion

Main Points Raised

  • One participant notes that a 3rd degree polynomial is called a cubic and questions why a 2nd degree polynomial is termed quadratic, given the prefix "quad" implies four.
  • Another participant explains that the term "quadratic" derives from the Latin word "quadratus," which means "square," indicating a connection to the area of squares.
  • A later reply expresses gratitude for the explanation and includes a light-hearted comment about the responder's screen name.
  • Further interaction reveals a friendly exchange, with one participant confirming they did not create their screen name solely for this discussion.

Areas of Agreement / Disagreement

Participants appear to agree on the etymology of "quadratic," but the initial question regarding the use of "quad" remains a point of curiosity without further exploration of differing views.

Contextual Notes

The discussion does not delve into deeper mathematical implications or alternative interpretations of the term "quadratic." The connection to geometric concepts is mentioned but not elaborated upon.

A 3rd degree polynomial is called a cubic, and a 2nd degree is a quadratic. But quad implies 4. Why is a 2nd degree called quadratic?

The word comes from the Latin word quadratus, meaning "square". Quadratic functions deal with calculating the area of squares.
 
Thank you! You didn't make up that screen name just to answer my question, did you :)
