Давайте рассмотрим геометрический смысл производной.Начнем с графика квадратичной функции y равно x в квадрате.Возьмем точку на графике функции.Если мы возьмем другую точку на графике и проведем через них секущую линию...При приближении второй точки к первой, секущая начинает приближаться к касательной.В пределе, когда точки бесконечно близки, секущая становится касательной к графику функции.Производная функции в точке - это угловой коэффициент касательной, который мы находим как предел отношения приращения функции к приращению аргумента.Этот угол наклона касательной и определяет значение производной в данной точке.Now let's understand how derivatives represent instantaneous velocity.Consider an object's motion represented by this curve, where distance is a function of time.Let's first look at average velocity over a large time interval.The average velocity is the change in distance divided by the change in time.As the time interval becomes infinitely small, we get the instantaneous velocity, represented by the slope of this tangent line.The instantaneous velocity is the limit of the average velocity as the time interval approaches zero.Let's explore the basic rules for calculating derivatives.For example, the derivative of any constant, like 5, is always zero, since constants don't change.Now, let's solve a more complex example: finding the derivative of x squared plus two x.Let's visualize both the original function and its derivative on a graph.Let's review the key points about derivative rules.Thanks for learning derivative rules with Spark.E!
