I created this thread for anyone that is interested in discussing mathematics. I don't think that this thread is a [dup] and if it is, it was not intended to be one.
The first thing I will say is that I know the value of:
e to 12 digits: 2.718281828459
pi to 25 digits: 3.1415926535897932384626433
I hope that this thread will be a successful one.

its irrational the same reason the square root of 2 is


An irrational number is simply one that cannot be accurately expressed as a fraction. Nothing more, nothing less.

Math. It's been awhile since I did some math. I just remember some stuff about radians be equated to the angle subtended by an arc. Arc length divided by the radius of the arc.

Some other notable topics I remember:
Integrals, triple integration, hypervolume, and Jacobian matrix and determinant.

I should have studied harder, it's a fuzzy memory now.

Circular logic. I want to know why it has no pattern. Why are the numbers after pi what they are.


I remember learning they used a method called exhaustion to discover pi but i don't remember how that worked. If you want to learn how, go take a class in calculus.

Now this number of pi digits is amazing. It is 1,000,000 digits. =O

How many people here knows what e stands for? (2.718281828459...) (I know the answer.)

Napier's constant.

Here's a simple question on matrices.

A 3 x 3 skew-symmetric matrix is non-singular. True or False?

51948/78

The answer is:666.
BTW, I don't think that that is a huge division problem.

Correct answer. How is that problem not huge?

With improved knowledge, I have this one:
