# Nonlinear algebraic equations

### From Process Model Formulation and Solution

## [edit] Taylor series review

*We will start this section of the course with a review of Taylor series (1 class). The Taylor series notes will also be useful for later sections in the course.*

## [edit] Nonlinear algebraic equations

*But these notes are the bulk of this section.*

*Reference in course textbook for multivariable nonlinear systems, using Newton's method*

Unfortunately, the course textbook has poor treatment of this topic due to the fact they treat nonlinear equations before linear equations! So it is spread over two parts:

- section 6.6 (page 167 in the 6th edition)
- section 9.6 (page 267 in the 6th edition)
