Chapter 8 Exercise 4

[jkiley]

Note:  I have the second printing.

In a future version, could you add a sentence or two to Chapter 8 Exercise 4 briefly explaining what you mean by vector and translation.  I looked at the examples of others and googled, but it might be helpful for those of us who haven't been in a Calc class in some time.

For example, you might add this sentence to the end of the exercise:

Translation using a vector moves the entire rectangle within the coordinate plane by adding each of the vector's coordinate values to the corresponding coordinates of the rectangle's origin.

Yes, I will clarify it in a future printing.  Did you look at this thread:

By the way, this isn't calculus terminology; it's really geometry (and terminology used in graphics programming).  Nevertheless, I will explain it more fully in the future.

Cheers,
