May 2, 2015 · Okay this may sound stupid but I need a little help... What do $\Large \frac {d} {dx}$ and $\Large \frac {dy} {dx}$ mean? I need a thorough explanation. Thanks.

微分的定义中，dx与 x到底是什么关系？ 众所周知，微分符号dx、dy，还有积分符号∫，都是威廉·莱布尼茨的发明. 对于莱布尼茨的符号体系，后世给予的评价是四个字：简洁准确. 设y=f（x），x∈D. ⭕️ …

A "signed definite integral" for computing work and other "net change" calculations. The value of an expression such as $\int_0^1 x^2\,dx$ comes out the same under all these interpretations, of course. …

d/dx后面肯定跟这个括号 例如d/dx (x²+1) 其实也就是让你求fx式子中对x的导。也就是 dx/dy=d/dx (f (x))=f' (x),表达方式不同而已。

此时的绿色部分虽然仍是长方形，但是由于短边非常短，也许只有0.0000001，近似看做一条直线。而之前黑色的正方形呢？可以看做是一个黑色的点，一个肉眼不可见的黑色点。 现在考虑一下，对于红 …

微分运算中dy=AΔx+o(Δx)为什么不是dx？之前有的说dx就是极小的Δx随着逐渐的学习发现好像也不完全如此？

The symbol used for integration, $\int$, is in fact just a stylized "S" for "sum"; The classical definition of the definite integral is $\int_a^b f (x) dx = \lim_ {\Delta x \to 0} \sum_ {x=a}^ {b} f (x)\Delta x$; the limit …

I'm new to calculus, and I'm trying to understand the syntax of derivatives: $$\\frac {dy}{dx}$$ At a glance it implies some kind of division and some variable "d" has entered the picture. Does this

Aug 21, 2023 · S=F (b)-F (a)\triangleq\displaystyle\int_a^bf (x)\mathrm dx 所以不定积分和面积没任何关系，不定积分只是一个逆运算，是牛莱公式将曲边梯形面积和原函数联系到一起的。 换句话说，只 …
