The Venn diagram is a type of Euler diagram. While Euler may have been the first to use this type of diagram, it was John Venn who really brought it into the public eye.

It's similar to a Venn diagram as both use circles to create the diagram. However, while a Venn diagram represents an entire set, an Euler diagram represents a part of a set. A Venn diagram shows an empty set by shading it out, whereas in an Euler diagram that area could simply be missing altogether.

An Euler diagram (/???l?r/, OY-l?r) is a diagrammatic means of representing sets and their relationships. They are particularly useful for explaining complex hierarchies and overlapping definitions.

Euler diagrams, Eulerian circles and Euler's constant are named for Swiss mathematician Leonhard Euler (1707?1783). Both Venn and Euler diagrams were adopted for teaching set theory as part of the new math movement of the 1960s.

The argument is valid if and only if every possible diagram illustrates the conclusion of the argument. If there is even one possible diagram that contradicts the conclusion, this indicates that the conclusion is not true in every case, so the argument is invalid.

Euler diagrams consist of simple closed shapes in a two-dimensional plane that each depict a set or category. How or whether these shapes overlap demonstrates the relationships between the sets.

In general, Venn diagrams are ideal to visualize simple set relationships and can be useful for teaching basic concepts in set theory. However, Euler diagrams are more flexible and versatile, therefore they can be used to visualize a wider range of relationships between sets.

You can also show the r squared value if you want to work out how good your trend line actually is one is perfect.

To graph the equation, choose three values for x and list them in a table. (Hint: choose values that are easy to calculate, like ?1, 0, and 1.) Substitute each value in the equation and simplify to find the corresponding y-coordinate. Plot the ordered pairs and draw a straight line through the points.
