Michael Artin's Algebra Exercises

1 Matrices

Section 1 The Basic Operations

1.1. What are the entries \( a_{21} \), and \( a_{23} \) of the matrix A = \( \begin{bmatrix}
1 &2 &5 \\
2 &7 &8 \\
0 &9 &4
\end{bmatrix} \) ?

\( a_{21} = 2 \), and \( a_{23} = 8 \)

1.2. Determine the products AB and BA for the following values of A and B:

\( A = \begin{bmatrix}
1 &2 &3 \\
3 &3 &1
\end{bmatrix}, \hspace{2mm}
B = \begin{bmatrix}
-8 &-4 \\
9 &5 \\
-3 &-2
\end{bmatrix} \)

\( AB = \begin{bmatrix}
1 &0 \\
0 &1
\end{bmatrix}, \hspace{4mm}
BA = \begin{bmatrix}
-20 &-28 &-28 \\
24 &33 &32 \\
-9 &-12 &-11
\end{bmatrix} \)

\(
A = \begin{bmatrix}
1 &4 \\
1 &2
\end{bmatrix}, \hspace{2mm}
B = \begin{bmatrix}
6 &-4 \\
3 &2
\end{bmatrix}
\)

\( AB = \begin{bmatrix}
18 &4 \\
12 &0
\end{bmatrix}, \hspace{4mm}
BA = \begin{bmatrix}
2 &16 \\
5 &16
\end{bmatrix} \)

1.4. Verify the associative law for the matrix product

\( ABC = \begin{bmatrix}
1 &2 \\
0 &1
\end{bmatrix}
\begin{bmatrix}
0 &1 &2 \\
1 &1 &3
\end{bmatrix}
\begin{bmatrix}
1 \\
4 \\
3
\end{bmatrix} \)

Note: This is a self-checkingproblem.It won’t come out unless you multiply correctly. If you need to practice matrix multiplication, use this problem as a model.

\( (AB)C = \begin{bmatrix}
2 &3 &8 \\
1 &1 &3
\end{bmatrix}
\begin{bmatrix}
1 \\
4 \\
3
\end{bmatrix}
= \begin{bmatrix}
38 \\
14
\end{bmatrix}
= 2 \begin{bmatrix}
19 \\
7
\end{bmatrix}
\)

\( A(BC) = \begin{bmatrix}
1 &2 \\
0 &1
\end{bmatrix}
\begin{bmatrix}
10 \\
14
\end{bmatrix}
= \begin{bmatrix}
38 \\

\end{bmatrix}
= 2 \begin{bmatrix}

刻几何原本序

唐、虞之世,自羲、和治曆,暨司空、后稷、工、虞、典乐五官者,非度数不为功。《周官》六艺,数与居一焉;而五艺者,不以度数从事,亦不得工也。襄、旷之于音,般、墨之于械,岂有他谬巧哉?精于用法尔已。故尝谓三代而上,为此业者盛,有元元本本、师傅曹习之学,而毕丧于祖龙之焰。汉以来,多任意揣摩,如盲人射的,虚发无效;或依拟形似,如持萤烛象,得首失尾。至于今而此道尽废,有不得不废者矣。

《几何原本》者,度数之宗,所以穷方圆平直之情,尽规矩准绳之用也。利先生从少年时,论道之暇,留意艺学,且此业在彼中所谓师傅曹习者,其师丁氏,又绝代名家也,以故极精其说。而与不佞游久,讲谈余晷,时时及之。因请其象数诸书,更以华文。独谓此书未译,则他书俱不可得论,遂共翻其要约六卷,既卒业而复之,由显入微,从疑得信。盖不用为用,众用所基,真可谓万象之形囿,百家之学海。虽实未竟,然以当他书,既可得而论矣。

私心自谓,不意古学废绝二千年后,顿获补缀唐、虞、三代之阙典遗义,其裨益当世,定复不小。因偕二三同志,刻而传之。

先生曰:「是书也,以当百家之用,庶几有羲、和、般、墨其人乎,犹其小者,有大用于此,将以习人之灵才,令细而确也。」余以谓小用大用,实在其人。如邓林伐材,栋梁榱桷,恣所取之耳。顾惟先生之学,略有三种,大者修身事天,小者格物穷理。物理之一端,别为象数,一一皆精实典要,洞无可疑,其分解擘析,亦能使人无疑。而余乃亟传其小者,趋欲先其易使人绎其文,想见其意理,而知先生之学可信不疑。大概如是,则是书之为用更大矣。他所说几何诸家,藉此为用,略具其自叙中,不备论。
