Main Translations

English: Coefficient

Thai: สัมประสิทธิ์ (Sampraphit)

Phonetic: Sum-pra-sìt (pronounced with a rising tone on "sìt")

Detailed Explanation: In English, "coefficient" refers to a numerical factor or multiplier in a mathematical expression, such as the "2" in the equation 2x + 3. It is commonly used in scientific, engineering, and statistical contexts to denote a constant that scales a variable. Usage scenarios include algebra, physics (e.g., drag coefficient in aerodynamics), and economics (e.g., regression coefficients). Emotionally, it carries a neutral, technical connotation, emphasizing precision and analysis. Semantic nuances involve its role in quantifying relationships, making it essential in data-driven fields. In Thai, "สัมประสิทธิ์" is directly borrowed for similar purposes, often in educational or professional settings, with no significant emotional undertones.

References

Etymology and History:

The word "coefficient" originates from the Latin "coefficientem," meaning "cooperating" or "working together," derived from "co-" (together) and "efficiens" (efficient). It entered English in the 17th century through mathematical texts, evolving to represent multipliers in algebra. In Thai, it was adopted in the 20th century with Western influences in education.

Literary References:

In scientific literature, such as Isaac Newton's "Principia Mathematica," coefficients appear in equations describing motion. A modern example is in Albert Einstein's relativity papers, where coefficients model physical constants. In Thai contexts, it's referenced in textbooks like those by the Thai Ministry of Education, e.g., "Mathematics for High School Students," illustrating its role in equations.
