# Linear Algebra Formulas

### 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.

**Linear algebra formulas**.
If you studied the writing equations unit you learned how to write equations given two points and given slope and a point.
Linear algebra is the foundation of science and engineering.
In the previous lesson on functions you learned how to find the slope and write an equation when given a function.
