A。解析:对于函数\(y = uv\)(这里\(u = x^{2}\),\(v=\sin x\)),根据乘积法则\((uv)^\prime = u^\prime v+uv^\prime\)。\(u = x^{2}\)的导数\(u^\prime = 2x\),\(v=\sin x\)的导数\(v^\prime=\cos x\),所以\(y^\prime = 2x\sin x+x^{2}\cos x\)。选项B中符...
Derivative of natural logarithm ln x Derivative $f’$ of the function $f(x)=\ln x$ is: \(\forall x \in ]0, +\infty[ , \quad f'(x) = \dfrac{1}{x}\) Proof Let $y$ the function ln x $y = f(x)= \ln x$ then by definition (ln is the inverse function of exp) ...

Notice how the slope of each function is the y-value of the derivative plotted below it.For example, move to where the sin(x) function slope flattens out (slope=0), then see that the derivative graph is at zero. A similar thing happens between f'(x) and f''(x). Try this at ...
