hằng lượng

Friendly

The Vietnamese word "hằng lượng" translates to "constant" in English, particularly in the context of mathematics and science. It refers to a value that does not change, regardless of the circumstances or conditions.

Basic Explanation:

• Meaning: In mathematics, a constant is a fixed value that does not vary. For example, in the equation (y = 2x + 3), the number 3 is a constant because it remains the same no matter what value x takes.

Usage Instructions:

• Where to Use: You can use "hằng lượng" when discussing mathematical equations, physics formulas, or any situation where a value remains unchanged.
• Example:
  • "Trong phương trình (y = ax + b), (b) là một hằng lượng." (In the equation (y = ax + b), (b) is a constant.)

Advanced Usage:

• In more advanced mathematics, constants can be used in calculus, statistics, and physics. For instance, the value of π (pi) is a mathematical constant that represents the ratio of a circle’s circumference to its diameter.

Word Variants:

• Hằng số: This is another term for "constant" and is often used interchangeably with "hằng lượng." Both terms can refer to a fixed value.
• Biến: This means "variable," which is the opposite of "constant." Variables can change, while constants do not.

Different Meanings:

• While "hằng lượng" primarily refers to a mathematical constant, in broader contexts, it can also imply stability or permanence in a situation or condition.

Synonyms:

• Hằng số: As mentioned earlier, this is a synonym and is commonly used in mathematical contexts.
• Không đổi: This means "unchanging" or "constant," and can be used in both mathematical and everyday contexts.

Example Sentences:

1. "Trong vật lý, hằng lượng Planck là một hằng lượng quan trọng trong cơ học lượng tử." (In physics, Planck's constant is an important constant in quantum mechanics.) 2.
