( -z((x-y))^2-1x^2z+2xyz-1y^2z+2xyz-1y^2z+y-k=-y^2z) This is the form of a hyperbola. Use this form to determine the values used to find vertices and asymptotes of the hyperbola. ( (((x-h))^2)(a^2)-(((y-k))^2)(b^2)=1) Match the values in this hyper...
( x^2+y^2-y=0) Complete the square for ( y^2-y). ( ((y-1/2))^2-1/4) Substitute ( ((y-1/2))^2-1/4) for ( y^2-y) in the equation( x^2+y^2-y=0). ( x^2+((y-1/2))^2-1/4=0) Move ( -1/4) to the right side of the equation by adding ( 1/...
在Plotly中,可以使用X、Y和Z数组来绘制三维曲面。下面是一个完整的步骤: 导入所需的库和模块: 代码语言:txt 复制 import plotly.graph_objects as go import numpy as np 创建X、Y和Z数组: 代码语言:txt 复制 # 创建X和Y的网格 x = np.linspace(-5, 5, 100) y = np.linspace(-5, 5, 100) X...
float zValue; glReadPixels(x, y, 1, 1, GL_DEPTH_COMPONENT, GL_FLOAT, &zValue); 其中,x和y是点的屏幕坐标,zValue是获取到的Z坐标值。 需要注意的是,以上代码只适用于获取当前渲染帧的Z坐标值。如果需要获取之前渲染帧的Z坐标值,可以使用帧缓冲区对象(framebuffer object)来保存深度缓冲区的内容。 总...
首先可由2(2−x2)=2(y2+z2)≥(y+z)2=(2−x)2解得x≥0,于是0≤x<1.接着，又由xy+yz+zx=(x+y+z)2−(x2+y2+z2)2=1xy+yz+zx =\frac{(x+y+z)^2-(x^2+y^2+z^2)}{2}=1\\得到yz=1−xy−zx=1−x(y+z)=1−x(2−x)=(1−x)2.yz=1-xy-zx=1-x(...
SOLUTION To find the trace in the xy-plane, we set z =0 in the given equation. The graph of the resulting equation (x^2)/(16)+(y^2)/(25)=1 is an ellipse. The traces in the xz-plane and the yz-plane (obtained by setting y = 0 and x = 0, respectively) are a...
