Mathematical Constants
Intriguing, ubiquitous, and at times mysterious, numerical constants set the allowable limits for all universal phenomena. Whether your questions involves π, Avogadro's number, Planck's constant, the atomic mass unit, or any of the other multitudes of immutable numbers used in science, this is the category where they should be asked.

Why is pi a approximate number?
Asked by Wiki User
If we were to write the whole thing, we would be here forever(literally!). So, we took it to a simple 3.14 or 22/7.
Why you restrict the argument of a complex number between -pi and pi?
Asked by Wiki User
Because the trigonometric functions (sine and cosine) are periodic, with period 2*pi. If the argument were not restricted, you would have an infinite number of answers.
You could, of course, restrict the argument to any interval of size 2*pi: 3.5pi to 5.5pi, for example.

Who founded universal gravitational constant?
Asked by Wiki User
Sir. Isaac Newton discovered the formula with the universal gravitational constant.
What are the different ways you can represent pi as a number?
Asked by Wiki User
The only one that I am aware of is the greek letter pi: π.
There are many approximations, such as 3.14 or 3.14159 or 22/7. There are many functions whose solutions involve pi and so can be used to calculate pi. There are also many infinite series that converge to pi or some function of pi. Some are given in the attached link. However, these are all approximations to pi.
What is ideal ratio?
Asked by Wiki User
There are different ideal ratios for different situations. For example, the ideal ratio of hydrogen to oxygen atoms, in water, is 2:1. The ideal ration for sodium and chlorine atoms for salt is 1:1.

What is the place value of 3.94 value?
Asked by Wiki User
A digit within a number has a place value, not the entire number - such as 3.94.
Why represented the integers by the symbol Z?
Asked by Wiki User
It's short for Zahlen, which is German for "numbers". Why German? Why not?
