Re: [問題] 有誰可以回答我線性代數的問題,幫一下 …

1.Each of the linear transformations in parts ( a )through ( e )
corresponds to one (and only one) of the matrices A through J.
Match them up.
每個線性變換的部分(a)至(e)對應一個(並且只有一個)的矩陣A J.比賽
他們通過成立
a.Scaling b.Shear c.Rotation d.Orthogonal projection e.Reflection
a.縮放 b.剪切 c.旋轉 d.正交投影 e.反射
2.In the financial pages of a newspaper,one can sometimes find a table
(or matrix) listing the exchange rates between currencies.In this
exercise we will consider a miniature version of such a table,involving
only the Canadian dollar (C$) and the South African Rand(ZAR).
Consider the matrix.
在金融頁報紙,有時可以找到一個表(或矩陣)上市的貨幣之間的匯率。
在這項工作中,我們會考慮一個微型版本了這樣一個表格,
只涉及加元(加元)和南非蘭特(人民幣)。考慮矩陣
3.Let L be the line in R3 that consists of all scalar multiples of
the vector {2 1 2}.Find the orthogonal projection of the vector
{1 1 1} onto L.
設L是R3中的行是由所有標倍數的向量(2 1 2)。找到正交投影向量的
(1 1 1)到L
4.Find the inverse of the linear transformation
求逆的線性變換
對不起,多弄了一篇多餘的,因為還不太會發文!
