WebA polar equation describes a curve on the polar grid. The graph of a polar equation can be evaluated for three types of symmetry, as shown in Figure 6.2.2. Figure 6.2.2: (a) A graph is symmetric with respect to the line θ = π 2 (y-axis) if replacing (r, θ) with ( − r, − θ) yields an equivalent equation.

Or: R-squared = Explained variation / Total variation. R-squared is always between 0 and 100%: 0% indicates that the model explains none of the variability of the response data around its mean. rich sumbitch wheeler walker jr

WebDec 21, 2024 · I have a graph and from the graph I have to read the coordinates of the point where 2 lines intersect and I have to save them in variables xm and ym. I would like to ask if someone could help me. WebThe reason R^2 = 1-SEl/SEy works is because we assume that the total sum of squares, the SSy, is the total variation of the data, so we can't get any more variability than that. When we intentionally make the regression line bad like that, it's making one of the other sum of square terms larger than the total variation.
