Practice Problem 2.4 (p.g. 34)

[MTDTMFH]

Hi there

Enjoying the book so far!

I believe b) should equal a column vector as [0 1 100] not [0 1 -20], as 0 - (-60) + (40) = 100

Great catch, thanks! I've actually already caught this one and it's updated in the most recent version.

Thought I was going crazy for a min so good to hear.

Thanks for the prompt response. I ended up buying the course too :))

Hi! I came here for the same, but then saw this issue outstanding... Thank you so much for the book - I love it!

Thanks jrozra. I have made a smattering of other minor adjustments to the book and plan on updating it in the next 1-2 months. Don't worry -- no major changes that would make it be called a 2nd edition.

On the version I have, it's the other way around:
In the book we have:
b) [4 2 0] - [6 -4 60] + [2 -5 40] = [0 1 100]

But the solution (I hope) should be [0 1 -20], as 0 - 60 +40 = -20
