A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity. Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations. The history of an object's location through time traces out a line or ...
Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius. Cartesian coordinates are named for René Descartes, whose invention of them in the 17th century revolutionized ...
The layout usually consists of evenly spaced horizontal lines, or feints, with vertical lines drawn to indicate margins, the middle of the page, or sections of a line. Graph paper has horizontal and vertical lines evenly spaced over the entire page to create a grid of squares and is used for drafting, drawing and plotting graphs. Often every ...
ordinate-axis (vertical) coordinate. Usually these are the horizontal and vertical coordinates of a point in plane , the rectangular coordinate system . An ordered pair consists of two terms—the abscissa (horizontal, usually x ) and the ordinate (vertical, usually y )—which define the location of a point in two-dimensional rectangular space:
The graph of a real function f, the set of points (, ()) , is often pictured in the real coordinate plane with x as the horizontal coordinate and = as the vertical coordinate. Starting from the graph of f, a horizontal translation means composing f with a function , for some constant number a, resulting in a graph ...
Chart. A pie chart showing the composition of the 38th Parliament of Canada. A chart (sometimes known as a graph) is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart ". [1] A chart can represent tabular numeric data ...
In science and engineering, a log–log graph or log–log plot is a two-dimensional graph of numerical data that uses logarithmic scales on both the horizontal and vertical axes. Power functions – relationships of the form – appear as straight lines in a log–log graph, with the exponent corresponding to the slope, and the coefficient ...
The linear–log type of a semi-log graph, defined by a logarithmic scale on the x axis, and a linear scale on the y axis. Plotted lines are: y = 10 x (red), y = x (green), y = log (x) (blue). In science and engineering, a semi-log plot / graph or semi-logarithmic plot / graph has one axis on a logarithmic scale, the other on a linear scale.
