Methods for solving cubic equations appear in The Nine Chapters on the Mathematical Arta Chinese mathematical text compiled around the 2nd century BC and commented on by Liu Hui in the 3rd century. Some others like T.
More examples Once your statistical analyses are complete, you will need to summarize the data and results for presentation to your readers.
Data summaries may take one of 3 forms: Some simple results are best stated in a single sentence, with data summarized parenthetically: Seed production was higher for plants in the full-sun treatment Tables present lists of numbers or text in columns, each column having a title or label.
Do not use a table when you wish to show a trend or a pattern of relationship between sets of values - these are better presented in a Figure. For instance, if you needed to present population sizes and sex ratios for your study organism at a series of sites, and you planned to focus on the differences among individual sites according to say habitat type, you would use a table.
However, if you wanted to show us that sex ratio was related to population size, you would use a Figure.
Graph definition, a diagram representing a system of connections or interrelations among two or more things by a number of distinctive dots, lines, bars, etc. See more. Linear function interactive app (explanation below): Here we have an application that let's you change the slope and y-intercept for a line on the (x, y) plane. You change these values by clicking on the '+' and '-' buttons. After each click the graph will be redrawn and the equation for the line will be redisplayed using the new values. The following links provide quick access to summaries of the help command reference material. Using these links is the quickest way of finding all of the relevant EViews commands and functions associated with a general topic such as equations, strings, or statistical distributions.
Figures are visual presentations of results, including graphs, diagrams, photos, drawings, schematics, maps, etc. Graphs are the most common type of figure and will be discussed in detail; examples of other types of figures are included at the end of this section.
Graphs show trends or patterns of relationship. Once you have done your analyses and decided how best to present each one, think about how you will arrange them.
Your analyses should tell a "story" which leads the reader through the steps needed to logically answer the question s you posed in your Introduction.
The order in which you present your results can be as important in convincing your readers as what you actually say in the text. How to refer to Tables and Figures from the text: Use sentences that draw the reader's attention to the relationship or trend you wish to highlight, referring to the appropriate Figure or Table only parenthetically: Germination rates were significantly higher after 24 h in running water than in controls Fig.
DNA sequence homologies for the purple gene from the four congeners Table 1 show high similarity, differing by at most 4 base pairs. Avoid sentences that give no information other than directing the reader to the Figure or Table: Table 1 shows the summary results for male and female heights at Bates College.
Abbreviation of the word "Figure": When referring to a Figure in the text, the word "Figure" is abbreviated as "Fig. Both words are spelled out completely in descriptive legends. Top of Page How to number Tables and Figures: Figures and Tables are numbered independently, in the sequence in which you refer to them in the text, starting with Figure 1 and Table 1.
If, in revison, you change the presentation sequence of the figures and tables, you must renumber them to reflect the new sequence.
Placement of Figures and Tables within the Paper: In consideration of your readers, place each Table or Figure as near as possible to the place where you first refer to it e.
It is permissable to place all the illustrative material at the end of the Results section so as to avoid interrupting the flow of text. The Figures and Tables may be embedded in the text, but avoid breaking up the text into small blocks; it is better to have whole pages of text with Figures and Tables on their own pages.
The "Acid Test" for Tables and Figures: Any Table or Figure you present must be sufficiently clear, well-labeled, and described by its legend to be understood by your intended audience without reading the results section, i.
Overly complicated Figures or Tables may be difficult to understand in or out of context, so strive for simplicity whenever possible.
If you are unsure whether your tables or figures meet these criteria, give them to a fellow biology major not in your course and ask them to interpret your results.The HASPI Curriculum Resources are available free for use by educators.
All of the resources align with the Next Generation Science Standards (NGSS) and Common Core State Standards (CCSS). Determining the Equation of a Line From a Graph. Determine the equation of each line in slope intercept form.

plot the data, letting x = 0 correspond to the year , find a quadratic function that models the data,; plot the function on the graph with the data and determine how well the graph fits the data, ; use the model to predict the cumulative number of AIDS cases for the year The following links provide quick access to summaries of the help command reference material.
Using these links is the quickest way of finding all of the relevant EViews commands and functions associated with a general topic such as equations, strings, or statistical distributions. The graph of f is shown below. Notes that 1) As x approaches 3 from the left or by values smaller than 3, f (x) decreases without bound.
2) As x approaches 3 from the right or by values larger than 3, f (x) increases without bound. In algebra, a cubic function is a function of the form = + + +in which a is nonzero.. Setting f(x) = 0 produces a cubic equation of the form + + + = The solutions of this equation are called roots of the polynomial f(x).If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd degree polynomials).
