\(x \in R^n\), they define \(\vec x =(x_1, x_2)\) and by definition above \(\vec x \in R^n\) must have n-tuples, that is \(\vec x =(x_1,x_2,......,x_n)\) so that if it stops at \(x_2\), then the tuples after it will repeat \(x_2\) in n-1 times. Why n-1? because you have \(x_1 \) there.

Hello

Like in \(\mathbb R^3\), \(vec x =(x_1,x_2,x_3)\) , in topology, if they say \(\vec x=(x_1,x_2)\) \(\in \mathbb R^3\), that is \(vec x=(x_1,x_2,x_2)\), hence \(x_2\) repeats n-1 =3-1=2 times. Got that part??

sir, why did x2 repeat twice?
Loser66
  • Loser66
They define it that way!! like your parents "define" you are GIL.
Loser66
  • Loser66
so that everybody will call you GIL. That is it.

  • anonymous
is it from the definition x(x1,x2) den because it is not up R^3
anonymous
  • anonymous
which ought to be (x1,x2,x3)?

Actually, this book is not good. If it is written in other language, I have no comments. But it is written in English, but they changed tuple to topple; scalar to sealar. At the first read, I didn't understand what it means. ha!!

sir please have pity on my and help me out or if you have any self teachable book, you can help with , please do. it means i have to understand this before understanding matric and topological space
Loser66
  • Loser66
Anyway, it is just the way they define the operator. it is not important because it doesn't apply to any other problem.
Loser66
  • Loser66
Again, it is not matric!! it is metric.

  • anonymous
ok sir

One more thing!! I didn't take topology yet!!. My friends warned me not to take that course. It is so confused and apply to nowhere.
anonymous
  • anonymous
hahahahahahaah. but it is a call course for me . i have to learn it . ok can you take me metric space?
Loser66
  • Loser66
To the topic I never know before, I can make a SHORT research to know what it is. Don't forget, SHORT, not long.

ok but can you open to page 14 of the book, under remark ,,,, i dont get a thing there
