(i) 曲线在x=4处的斜率为64。 (ii) 曲线的两个极值点的坐标为(0,6)和(4/3,-22/27)。 (i) 曲线在x=4处的斜率即为导数在x=4处的值。求导得 dy/dx = 6x² - 8x,代入x=4,得到斜率为64。 (ii) 极值点对应导数为0的点。解方程 6x² - 8x = 0,得到x=0 或 x=4/3。将这两个...
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 ...

The Gradient Theorem: Suppose that {eq}f {/eq} is a continuously differentiable function, and {eq}C {/eq} is an oriented curve in the domain of {eq}f {/eq}. Let the starting point of {eq}C {/eq} be ...
Similar todiff, thegradientfunction requires numerical data points. We can calculate the gradient of a functionfusing the following code: matlab [gx, gy] = gradient(f, x, y); The resulting vectorsgxandgycontain the approximated partial derivatives with respect toxandy, respectively. ...
1 A-LEVEL的数学题The equation of a curve is y =6/(5 - 2x)(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 ofy has a constant value of 0.02 units per second.Fi...
worldToProjectionMatrix A matrix that transforms from world space to projection space, from which the planes will be calculated. Returns Plane[] The planes that enclose the projection space described by the matrix. Description Calculates frustum planes. This function returns six planes of a frustum...
Hypsometric tinting or Layer tinting isa method of showing relief on maps and charts by coloring in different shades those parts that lie between different levels. Sometimes referred to as elevation tint, altitude tint, and layer tint, color gradients, and gradient tints. ...

Additionally, we show that the indentation size effect may be well-represented by the strain gradient plasticity theory whereas significant deviation is observed when only partial depth-corrections are made.doi:10.1016/j.mechmat.2007.07.002D. Chicot...
