Google might give 73,482 results in 0.89 seconds.Going through each free portal and reading through License and Terms and conditions is painful job.

Hi,
Is there any free portal application which we can use for intranet application?
to do:
1)Logging of user
2)User will enter data in some table
3)Data will be stored in database table.
Regards

I thought about this:
e^ix = cos(x) + i sin(x) and then ix = ln(cos(x) +i sin(x)) and then put x = PI,you get the above one.But without this plugging,formula doesn't seem obivious to me.One irrational number raised to the power of another irrational and sqrt(-1) is -1?
As per Gauss- "if this formula was not immediately obvious, the reader would never be a first-class mathematician".

So you want to do R&D in how often people use the term "R&D" ?
I think its usage is more common in India(that too in IT companies).Possibly because we don't find the precise word in specific context??
The term Research and Development is much more than installing and configuring I believe.R&D assumes you know the present work and you are doing the research and later you will develop that.

Correct.Its difficult to predict long term future.Currency value depends on lot of factors such as oil,export,unemployment,agriculture etc.Making Saturday working I believe no company has taken the decision.The typical "wait and see" approach makes sense.

Thanks.When I took math classes,I never thought of PI beyond 3.14 and its ratio of circumference to diameter .Now I really wonder how Euler arrived at this formula?
e^ipi = -1 where e is natural logarithm(which is again irrational number) and i is squre root of -1 and PI again is irrational!!
From the same book:
"Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don't know what it means. But we have proved it, and therefore we know it must be the truth." �Benjamin Pierce, a Harvard mathematician, after proving Euler's equation, eiπ = �1, in a 19th-century lecture.

Contact B saying that you need to take career decision immediately hence B should reply.They will reply positive if you are their preferred candidate.If they delay saying on some "standard HR process" make sure they are still waiting for perfect candidate.

I was surprised to read in the book that Bible contains references to PI.
There are many formulas to find the value of PI.Most people used value of PI given by Archimedes.(who constructed inscribed and circumscribed 96-gon).(3 + 10/71) < PI < (3+ 1/7).
When we say value x of PI is better than y,which value of PI you are considering? The above one ?

Write a program to find that ratio.

MBA from the 'right' institute at 'right' time adds a value if you are in India.Distance learning from Symbiosis or IIM is a good option.Specialization in subjects such as Retail/cyber laws/e-security will be in demand in future everywhere.

If I recall correctly, you need to multiply by 4 if you're using a 1/4 th of a circle to do the calculation ( wich makes things simpler). Anyway, you need to discuss how acurate is your random number generator.
What is your goal?


Yes,thats Monte Carlo method.Goal is to find how accurately you generate the value of PI.The larger square you have and more points you select ,more accurate will be the value of PI.

Supercomputers are able to calculate the digits of Pi upto trillion digits.What are the various methods to calculate the value of PI?There are many methods described in this book.
Problem:Choose a square as large as possible and circle inscribed in it.Arrow is randomly hit.Either it hits inside or outside the circle.Ratio of area of square to circle is same as total hits to the hits inside/on the circle.so primary calculation gives the value of PI as 4*(total hits/total hits inside/on the circle)
Write a program to find the value of PI.

These problems frquently arise even while doing offshore projects.This happens because either:
1)Contracting company has told them to mind only their work,no less,no more.(So if I am .NET developer I need exact specification what should I code and what not.If something changes later I am not responsible). or

2)There is a fear that if (s)he takes the initiative and latter something fails (s)he will be asked to go out of project.or

3)As Tim said Asian mind set.(Contrary to Western work culture,I have seen many people(us,Indians) work(and perform) better in chaos type environment.)These contractors may be new hence might take some time to adjust to new culture.

I believe its combination of all these three which prohibits them to take the lead/initiative.
