why we use semi log graph?

In science and engineering, a semi-log plot, or semi-log graph (or semi-logarithmic plot/graph), has one axis on a logarithmic scale, the other on a linear scale. It is useful for data with exponential relationships, or where one variable covers a large range of values.

Coordinates. All graphs have an x and y axis. Coordinates, written as an ordered pair of numbers, are used to give positions on a graph. The x-axis is horizontal (across), while the y-axis is vertical (up-down).

The most common discrete graphs are those that represent sequences and series. These graphs do not possess a smooth continuous line but rather only plot points above consecutive integer values. Values that are not whole numbers are not represented on these graphs.

No, every straight line is not a graph of a function. Nearly all linear equations are functions because they pass the vertical line test. The exceptions are relations that fail the vertical line test.

There are many ethical issues that we should consider when creating a graph of data. The most important in my eyes is data accuracy. Failing to report or not having accurate data can be misleading. If someone is completing a graph and data is inaccurate it can throw someone's project completely off.

Yes constant time i.e. O(1) is better than linear time O(n) because the former is not depending on the input-size of the problem. The order is O(1) > O (logn) > O (n) > O (nlogn).

Natural logarithms are denoted by ln. On the graphing calculator, the base e logarithm is the ln key. All three are the same. If you have the logBASE function, it can be used to enter the function (seen in Y1 below).

The domain of the graph y = log (x) is therefore (0, ∞) and the range of the graph is (-∞, ∞). The x-intercept is located at x = 1, there is no y-intercept, and there is a vertical asymptote at x = 0.

Log(32/4) is equal to log(8) when 32 is divided by 4, log(32)-log(4) when we use the property of log (log(a/b) = log(a) - log(b), 3*log(2) when we use the property of log log(a^n) = n*log(a) after we have simplified Log(32/4) to log(8).

Line graphs can also be used to compare changes over the same period of time for more than one group. . . . a Pie Chart. Pie charts are best to use when you are trying to compare parts of a whole.

There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things.

Our firelogs are designed to burn as one whole log. If they are cut in half, it can affect the structural integrity of the product. This in turn will affect its performance, making it more likely for the product to break apart while burning and perhaps flare up. Therefore, we don't recomme… see more.

Answer: The second graph represents an odd function. The graph of an odd function will always be symmetric about the origin.

log (x^2) is not always 2log(x) as first one is defined for negative and positive both types of real x but the second one is defined only for positive x. So, log (x^2)=log (|x|^2)=2log(|x|) so log (x^2) and 2log(|x|) both are now same functions. Thanks.

Bar graphs use rectangular blocks to represent many different types of data, whereas line graphs use lines and represent trends over time particularly well.

A line graph is commonly used to display change over time as a series of data points connected by straight line segments on two axes. The line graph therefore helps to determine the relationship between two sets of values, with one data set always being dependent on the other set.
