Calculate the gradient of the curve y=x√(x+3) at the point where x = 1. Find the coordinates of the point at which the gradient is zero. 相关知识点: 试题来源: 解析 y=x√(x+3)Using ∴At the point where x=1,(dy)/(dx)=9/4. So the gradient at this point is 21/4.When ...
关于向量求曲线斜率的题目 已经给出向量方程r(θ)= cosθi + 3sinθj 然后θ=30度 求这个方程的斜率也就是gradient of the curve.cosθi + 3sinθj 就是x^2+Y^2/9=1.
(i) Calculate the gradient of the curve at the point where x=1.(ii) A point with coordinates (x,y) moves along the curve in such a way that the rate of increase of y has a constant value of 0.02 units per second.Find the rate of increase of x when x = 1.(iii) The region ...
从导数的定义证明，导数的定义就是由y(x+△x)趋近到y(x)在增量△x趋近于0时的趋近率，核心知识点就是求极限值，直线时候即是斜率值。则y'=lim△x→0[(y(x+△x))-y(x))/(x+△x-x)]=lim△x→0[((x+△x)n-xn)/△x]=nxn-1。(分子用Cknxk△x(n-k)拆开，很简单证明之)。
