In mathematics, the operation of finding the rate of change of a function (differentiation).
大学の微分の授業は導関数の概念から始まった。
The university course on differentiation began with the concept of the derivative.
この式をxで微分して解を求めなさい。
Differentiate this expression with respect to x and find the solution.
微分を使うと、変化の速さを数式で表せる。
Using differentiation, you can express rates of change mathematically.
A differential or derivative itself (for example, f'(x) is the derivative of f).
f(x)=x^2 の微分は f'(x)=2x である。
The derivative of f(x)=x^2 is f'(x)=2x.
微分を求めることで、関数の傾きが分かる。
By finding the derivative, you can understand the slope of a function.
