Integrate (using polar) z=1−x2−y2 inside a circle of r=1 centered at (0,0). Double Integrals in Polar Coordinates The integral of f(x,y) over a region in plane, R is ∬Rf(x,y)dA. If the region to integrate is bounded by a conic, then it i...
Consider the rational function( R(x)=(ax^n)(bx^m)) where ( n) is the degree of the numerator and ( m) is the degree of the denominator. 1. If ( n< m), then the x-axis, ( y=0), is the horizontalasymptote. 2. If ( n=m), then the horizontalasymptote is the line( y...
( -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...
Sketch the cylinder z=1−y2 Graph. The easiest way for plotting graph is to joining the coordinates derived from the given equation. This method becomes complex when the equation related to 3D plane or polar coordinates. Cylinder is the idealized version of a solid physical tin can having...
首先可以看因变量(Y)与解释变量(X)的关系,要保证其具有一定的相关性,即显著的。 其次可以看解释变量之间(X1和X2...)的相关性,可以显著也可以不显著,但是最好相关系数要小于0.8,超过0.8就说明其具有很强的相关性了,造成共线性的问题了。 1、双变量相关的可视化——Pearson矩阵散点图 ...

What is the graph of tthe function y = 2cos((pi/3) x) + 1? What is the graph of g(x)=f(2x)? Graph the level curves for z = f(x,y) = x + sin(y) for z = 0 and z = -1. What is a line graph? What would the value of A be in this graph?
01 —如何理解formula中y~.和y~x:z的含义? y~. 和 y~x:z 是一个简单的formula。~和 : 是formula中的运算符,但它们与通常理解的数学运算符存在一定的差距。...以下是formula中其他一些运算符的含义: ~ :~连接公式两侧,~的左侧是因变量,右侧是自变量。 + :模型中不同.
