Let V be a vector space and A,B be subsets of V .

prove that: span (A U B) = span (A) + span (B)

looks pretty obvious but dont know how to prove it using math

Thanks for the links. Khan academy has some really good videos on statistics.

Hi

I want to simulate a real world problem. People can enter a bank at any time between 8 am and 5 pm in the evening. More people are likely to come in the peak morning hours. So how do I get a distribution function for such a case.

I am looking for general ways of tackling this problem and not for a particular solution. I know basic probability but have very limited knowledge in statistics (know just basics like normal distribution, mean, variance)

And good to be back here after a long time

Yes, I used Geogebra too!

I have never noticed a heart like structure forming in my cup.

I will try to see that when I have tea tomorrow morning.

And there will also be two small traingles.

I have just edited it. Area took more time to do.

Hi gAr, I am getting an answer that is very similar to yours

I am sorry. You are right!

Is there something wrong with this website -

Hi gAr,

If we consider 2 cases, the years 400 and the year 2000. then y would be the same for both cases. But that would be a contradiction right?

Thank you, bobbym.

I learnt a new thing today!

**y = year (mod 400)** means y is the remainder when the year is divided by 400, right?

Hi,

I have a question - I have just looked up the internet for modulo operation.

So is

1)2000 mod 400 = 0

2)2004 mod 400 = 4?

Hi Krishnamr,

Hi

My engineering college will start within a month now. I saw Sage and it was a very large file. With my current internet speed I will not be able to finish downloading it before my college starts But I am very sure that the same file will be available inside the college. Hopefully I will also be able to get some decent reference book for Sage and C++ in the library there.

You have given me more options now and confused me a little. Thank you!

I will have a look at that book(TAOCP) in the future.

You guys know so much about computers!

Hi gAr,

Is GNU C fine for someone who uses Windows XP?

And which compiler should I use that is compatible with XP and is free too!

I had one more question - Which compiler should I use? I have Windows Vista Home Basic. But I may change it. So should I go for XP or 7?

I will try to find the books that you have mentioned.

Thanks again!

Hi bobbym and gAr,

Thank you.

I have decided to start with C++ because it will be used in our college more widely than other languages.

Do you know of any good book for introduction to C++?

Hi Bobbym,

Games? Utilities? Or Mathematical programming?

All of them fascinate me. But isnt there something that they have in common?

I would like to make simple applications like a simple calculator or something.

Or like writing a programme that gives all permutations of 'abcde'.
