To find the value of y at x=2 from the equation y=2x, follow these steps: 1. Identify the equation: The given equation is y=2x. 2. Substitute the value of x: We need to find y when x=2. Substitute x=2 into the equation: y=2(2) 3. Perform the multiplication: Calculate 2×...

Line graphs consist of two axes: x-axis (horizontal) and y-axis (vertical). Each axis represents a different data type, and the points at which they intersect is (0,0). The x-axis is the independent axis because its values are not dependent on anything measured. The y-axis is the ...
I'm working on a combination graph with two y-axes and have calculated the R2 value which included data from both y-axes data sets. I can't seem to add a trendline/ R2 value that incorporates both sets of data. Is this possible?
范数是一个标量,它是向量的长度或者模,$||x||$ 是 $x$ 在有限空间中坐标的连续函数。这里把 $x$ 简化成1维的,坐标之间的差值可以看作向量在空间中的距离,根据压缩映射的定义,可以导出: $$||F(x)-F(y)||{\leq}c||x-y||, 0\ {\leq}c<1$$ $$\frac{||F(x)-F(y)||}{||x-y||}{...
