What does non-rigid mean in math?

In the context of graphs, graphs are non- rigid when they can be stretched and deformed without changing the underlying graph structure. For example, a square on a piece of graph paper can be stretched while remaining a square. A graph is also non-rigid when the connection between two points on the graph can be stretched or deformed without changing the distance between the two points.

What does non-euclidean mean in math?

The idea of a non- euclidean geometry is that the sum of angles in a triangle is different from 180°. This allows for some triangles to have angles greater than 90°, which means that you can have a triangle that has three angles sum to more than 180°.

What does non-convergent mean in math?

A sequence of numbers that does not converge to a limit is said to be non-convergent. For example, the sequence is non-convergent since it gets closer and closer to the number -1 but never actually reaches it.

What does non-linear mean in math?

A function is nonlinear if it doesn’t have a linear relationship between its input and output. For example, the function f(x)=x^2 is nonlinear because the relationship between the input value and the output value is not linear. A line is an example of a linear relationship; the relationship between the input and output is always the same.

What does non-orthogonal mean in math?

A non-orthogonal coordinate system is a system of coordinates in which the lines that describe the axes are no longer all perpendicular to one another. For example, the sides of a cube represent the three coordinate axes of a non-orthogonal system. In this system, the length of one edge of the cube defines the length of the other two sides. This type of three-dimensional coordinate system is commonly used in computer graphics.
