Linear algebra is the study of lines and planes, vector spaces and mappings that are required for linear transforms. Equations like this are linear in that they describe a line on a two-dimensional graph.

Is Linear Algebra difficult?

The pure mechanics of Linear algebra are very basic, being far easier than anything of substance in Calculus. The difficulty is that linear algebra is mostly about understanding terms and definitions and determining the type of calculation and analysis needed to get the required result.

What is linear algebra used?

Combined with calculus, linear algebra facilitates the solution of linear systems of differential equations. Techniques from linear algebra are also used in analytic geometry, engineering, physics, natural sciences, computer science, computer animation, and the social sciences (particularly in economics).
