We study synthetic division and remainder theorem. This wraps up Chapter 7.
We review measuration, with the focus on:

We start a new chapter on polynomials. We review the basics of polynomial and talk about the login division.
We go over the application of vectors, particularly in geometry. Last week the substitute teacher did not get to go over this section.
Notice when vector AB = vector DC, it means line AB is parallel to line DC and AB = DC.
If you have not done your homework last week because you have some questions on certain problems, please do them now:

We study hyperbola. This concludes the chapter on conic functions.
We study circles and ellipses. More info in email.
We continue our study of vectors.
We can simplify the position of a point P on a plane by the vector OP where O is a reference point on the plane. The vector OP is called the position vector of P with respect to the reference point O. That is, every point on the plane can be represented by its position vector wrt the reference point O.
Then vector PQ = vector OQ – vector OP.
Furthermore, when we look at the coordinate plane for a point P (x, y), we can use its coordinates x and y to represent its position vector with respect to the origin O. We introduce column vector notation. A column vector is like a special form of a matrix (2 rows, 1 column). All matrix operations apply to column vectors.
We can apply what we have learned about vectors to help us solve geometry problems.
Notice when vector AB = vector DC, it means line AB is parallel to line DC and AB = DC.
