Vacation

Here I am, in Mexico City, with a very slow dial-up connection, so
there will not be much blogging around here. The pooch is here with me,
happy to be back home where he gets spoiled by my mom. I'm trying to
see as many doctors, family members and friends I can. I already went
downtown and got some Sinfonía yarn in a deep purple shade, but I
forgot to bring my camera so I cannot even show it here. I regret not
buying more, I got 600 grams for less than ten dollars.

No knitting content

Sorry, but other priorities have taken over. Still, I feel the need to blog about my current headache: Barron's Precalculus. I'm talking about this book. I wish I had read the reviews before buying it, because it really contains too  many mistakes. I searched for an errata page on Barron's webpage, and though they do have errata for some of their books, they don't for this one.

But I'm too stingy to get yet another book, and I'm not going to get one from the library because I like to write stuff on my own copy, so I'm sticking to this stinking book. In the meantime, I'll publish here the errata I come across, since no one else is bothering to do so. I'm skipping all the parts that require a graphing calculator since I won't be allowed to use a calculator during my test. Also, I do most of the checkup exercises, but not all of them. And finally, bear in mind that I'm not a math whiz and no one else is checking my own mistakes. That said, here I go:

Chapter 1:
Checkup exercises, No. 26:   0.2a 2-1.5ab

Chapter 2
Checkup exercises:
No. 3: 1/2√3
No. 10: (x-3y)/4
No. 15: -4
No. 41:4(x-2)

Chapter 3
Checkup exercies, No. 21: (9,2)

Chapter 4
Pg 92, division of two functions, I get 3x/(x 2-1), the domain is {x|x ≠1 and x≠-1}
Pg 102, factoring higher degree equations, I get x=2, x=-2, x=-1/3

This is as far as I got, but I'm sure there's more to come. I still vent some of my frustration by ocasionally spinning wool for the doggy rug, and there might be some knitting when I'm done.

Still here!

Yes, although I took a little blogging break. I didn't mean to, but you know how life is. First of all, I've been busy preparing a math test. I thought it would be easy, but I'm finding out my math is all rusty after all these years away from it. We also went to visit a friend in Miami (and surroundings) and had a great time.

But I got sick when I came back. I don't know what's wrong with me I usually get sick on airplanes. Which worries me, because very soon doggie and I are going to Mexico. That means the spouse will get a break from both of us because he's not coming.

There is very little progress with my knitting, as could be expected, but I will eventually finish a few things.
