derivative
含义: In calculus, the rate at which a function changes with respect to a variable, representing the slope of the tangent to the curve at any point. More generally, something derived from or based on another source.
The derivative is one of the two fundamental concepts in calculus, alongside the integral. It measures instantaneous rate of change and has applications across physics, engineering, economics, and biology. Outside mathematics, 'derivative' as an adjective often carries a negative connotation, implying something is unoriginal or imitative. It collocates with 'first,' 'second,' 'partial,' and 'financial' (as in derivative instruments).
