Definition The slope of curve $y=f(x)$ at the point $(x_0,f(x_0))$ is the number $$m=\lim_{h \rightarrow 0}\frac{f(x+ h)-f(x)}{h}$$ The tangent line to the curve at $P$ is the line through $P$ with this slope 함수 $y=f(x)$에서 $x=x_0$일 때, 미분계수(derivative of f at $x=x_0$) $f ' (x_0)$를 아래와 같이 정의한다. $$f ' (x_0) =\lim_{\Delta x\rightarrow 0}\frac{f(x_0+ \Delta x)-f(x_0)}{\Delta x}$$ $x=x_0$와 미분계수 $f ' (..
