We focus on speed-time graphs, how to read a speed-time graph, how to calculate the distance, how to draw a distance-time graph from a speed-graph, etc.

There are some homework that is about speed-time graph, please use last class’s homework sheets and do or redo the parts about speed-time graph.

We will have a quick review of statistics and probabilities next time. We will have our final exam on 6/18.

Here are some more homework:

We finish Chapter 7 by studying graphing and the Fundamental Theorem of Algebra, and applications of the Fundamental Theorem.

We study tables, charts, and graph, in particular we study distance-time graphs and speed-time graphs.

In our earlier classes (Math 7), students should have learned the basics of reading, interpreting and graphing of tables, charts, and graphs, as well as working with distance-time graphs.

So we focus on study speed-time graphs which can contain more information about the motion of an object than that of a distance-time graph.

With a speed-time graph, we can calculate acceleration, as well as calculating distance traveled, which is the area under the speed time graph.

We continue to study finding roots for polynomials. Today we study how to find rational roots, which are those that can be expressed as a fraction p/q, where p and q are relative prime.

We also study how to find certain bound for roots to help reducing the search space.

We start a new chapter on finding polynomial roots. We study the factor theorem, touch upon the fundamental theorem of algebra, and study how to find integer roots for polynomial with integer coefficients.
