Thnx bob and zetafunc.

I was learning differential calculus from mif when I saw this:

Why is the above point called f(x+Δx)?

Hi Abbas0000,

A polynomial is an algaebric expression in the form of

which satisfies 2 conditions-

•The powers of the variables are whole nos. (In this case

);and•The coefficients of the variables are Real nos. (In this case )

So any expression of the type satisfying the 2 conditions are classified as a polynomial.

If the variables are non-whole nos. and the coefficients are non-real nos. then the expression becomes too complex to be classified as a polynomial.

MIF has a website for science called ScienceHQ

Saw it. Hmm nice. I think the link should be mentioned in the mif website.

It may be a cost thing. The forum is free to join but the web-space has to be funded somehow. There are discrete, relevant adverts that do this. I wouldn't want the forum to become overwhelmed with adverts.

And you have to allow MIF himself to have a life outside the forum. Don't forget all those excellent pages take time to develop.

Bob

Hmm, I see. I can understand his hard work for creating the pages.

No, now I am master in calculus and geometry

Well, are you really a master in that...?

I think more topics of Physics could have been added. There are so so so so so many things in Physics but in MIF There are only a few.

I don't think it says this

Yes, it says that only.

Hmm.. the medium and the easy levels are too easy for me but the hard level is hard... Good!

Can anyone tell me the difference between a parabola and hyperbola?

It is more a mathematical problem of algebra than a puzzle.

You can find it out here:https://en.wikipedia.org/wiki/Maryam_Mi … earch_work

Hmm so sad. She was a great and rare woman mathematician. May her soul rest in peace!

You can also try one more formula for

It isYou cannot deny it.

Can u tell me how?

Hmm, excellent!

Actually there are 13. They all are listed below in brief.

1. A number of the nth row and nth position getting found out by Combiantion.

2.Existence of Fibonacci Sequence as bob showed above.

3.Shading Odd nos. in a Pascal's Triangle gives Sierpenski triangle series.

4.HCF of any row of a prime no. excluding 1 is that prime no. itself.

5.If you draw a hockey stick starting from an extreme end (that is a 1)and make a Hockey Stick,with only 1 number in the "J", the sum of all nos. in the stick = to the no. in the "J" of the hockey.

6.Adding nos. of the nth row give value as (2^n)

7.The nos. of the 2nd diagonal are the counting nos., the nos. in the 3rd diagonal are triangular nos., in the fourth are tetrahedral nos. and so on

8.The nos. of the nth row are the digits of 11^n.(From 11^5, it begans to overlap itself)

9.The pascal's triangle is symmetrical

10.Existence of catalan nos.

11.Pick any number inside Pascal’s triangle and look at the six numbers around it (that form alternating petals in the flowers drawn above). If you multiply the numbers in every second petal, you’ll end up with the same answer no matter which of the petals you start from.

12.Pick any counting number from along the first diagonal and square it. Then look at its two neighbours that lie deeper inside the triangle – they’ll always add up to that very same square number.

13.If you add up every single number in the first n rows, you’ll get the nth Mersenne number.

Aditya your mind is working extra fast it is symbol of colon dash and braces !!!!

What do you mean by "your mind is working extra fast"? Can you plzz tell me what is the actual use of this symbol :_(

I'm still learning.

What are you learning?

Made my first mistake today

What mistake did you make?

I think its the symbol for crying. Well, why are you crying?

Hi all,

I saw this post today and saw the probs on log. Well, they are not bad, they are good. But you can also try these problems here by me (Credit: to a book):

Oh bob,

You have changed your signature form "bob" to "B". Well, is it?

and CAT doesn't require the highest level of Geometry skills or Number theory skills. Beig familiar with UG level mathematics and to some extent PG level would do.

Hmm, its obvious because Cat opens the door for IIMs (best institute for management) just as IIT-JEE (or Jee advanced) opens the way for iits. There the problems are much tougher.
