Definition
- Noun:
- Derivative (in mathematics): In calculus, the "đạo hàm" is a fundamental concept that measures the instantaneous rate of change of a function with respect to one of its variables. It represents the slope of the tangent line to the graph of the function at a specific point.
Usage Examples
- Noun:
- Chúng ta cần tính đạo hàm của hàm số này. (We need to calculate the derivative of this function.)
- Đạo hàm của vận tốc theo thời gian là gia tốc. (The derivative of velocity with respect to time is acceleration.)
- Anh ấy đang giải thích khái niệm đạo hàm. (He is explaining the concept of the derivative.)
Advanced Usage
"Đạo hàm riêng" (Partial derivative): The derivative of a function of multiple variables with respect to one variable, while holding the other variables constant.
- Trong vật lý, chúng ta thường sử dụng đạo hàm riêng. (In physics, we often use partial derivatives.)
"Đạo hàm cấp cao" (Higher-order derivative): The derivative of a derivative, such as the second derivative or third derivative.
- Đạo hàm cấp hai cho biết độ cong của đồ thị. (The second derivative indicates the curvature of the graph.)
Variants and Related Words
- Vi phân (Differential): An infinitesimal change in a function, closely related to the derivative.
- Tích phân (Integral): A fundamental concept in calculus that is, in a sense, the inverse operation of differentiation (finding the derivative).
- Đạo hàm (verb form - to differentiate): While primarily a noun, it can be used in verb phrases like "tính đạo hàm" (to differentiate, to find the derivative).
Synonyms
- Tốc độ thay đổi tức thời (Instantaneous rate of change): A descriptive synonym for the core idea of a derivative.
Related Phrases
