Though abstract this definition of projection formalizes and generalizes the idea of graphical projection. Find materials for this course in the pages linked along the left. In linear algebra and functional analysis a projection is a linear transformation p from a vector space to itself such that p 2 pthat is whenever p is applied twice to any value it gives the same result as if it were applied once it leaves its image unchanged. Solving a linear function part 2. Linear functions are very much like linear equations the only difference is you are using function notation fx instead of y.

We are going to use this same skill when working with functions. This course covers matrix theory and linear algebra emphasizing topics useful in other disciplines such as physics economics and social sciences natural sciences and engineering. It parallels the combination of theory and applications in professor strangs textbook introduction to linear algebra.
