I am now in a Linear algebra class and don't understand the whole idea of transformations and[tex]R^{2}[/tex] [tex]R^{3}[/tex]. I really can't elaborate more as I don't have a clue.R meaning Reals
R^n refers to "n-dimensional Euclidean space," which is a mathematical concept used to describe the space in which we live. It is an infinite collection of points, each with n coordinates. For example, R^2 represents a two-dimensional plane, while R^3 represents a three-dimensional space.
The "n" stands for the number of dimensions in the Euclidean space. For example, R^2 has two dimensions, while R^3 has three dimensions.
R^n is a special type of space known as a "vector space." This means that it has certain properties, such as having a defined origin (the point (0,0) in R^2 or the point (0,0,0) in R^3) and being closed under addition and multiplication by a scalar.
R^n has many applications in mathematics, physics, and engineering. It is used to describe the physical world, as well as to solve problems in optimization, linear algebra, and differential equations. It is also used in computer graphics to represent 3D objects.
R^n is closely related to other mathematical concepts such as vectors, matrices, and coordinates. It is also used in conjunction with concepts like distance, angles, and transformations to describe and solve problems in various fields of study.
