Quantum theory says that at the interaction of the electron
with the vacuum, the energy and mass of it become infinite.
How can electron escape its infinity?
Pleas, remember, electron not a professional mathematician.
It maybe a particle, maybe a wave.

The fact that 2 was once not viewed as a prime number was described in the German book. Tropfke, J. Geschichte der Elementar-Mathematik, Band 1. Berlin, Germany: p. 96, 1921. Can any one provide a few English translations of sentences from that book that explains how was 2 not viewed as a prime in the past?
Can any one provide another source for the fact that 2 was once not a prime?

i dont understand how to do these.
are there important key rules i need to keep in mind?!
help me out here?
what should i look for?

ex: f(x)= squareroot x^2 +4

ex2: f(x)= x/x^2-5x

Gilbert the Gelert farmer (He's a Gelert who happens to be a farmer, not a farmer who grows Gelerts!) has three fields. One field is an equilateral triangle, one field is a circle, and one field is a square. The square field is 75% larger in area than the triangular field, and 50% larger in area than the circular field. In order to completely fence all three of the fields, exactly 4000 metres of fencing is required.

What is the total area of all three fields, in square metres?

find the domain and range of each function; ex: (-3, inf.]

1. f(x)= squareroot of x^2+4
2. h(x)= 5/x-3
3. f(x)= 3x-1/(x+3)(x-1)
4.f(x)= 1/x + 5/x-3
5. g(x)= x/x^2-5x
6. h(x)= squareroot 4-x^2 / x-3
[THE DENOMINATOR IS NOT UNDER THE RADICAL; only 4-x^2]

7.h(x)= squareroot 4-x/ (x+1)(x^2+1)
[THE DENOMINATOR IS NOT UNDER THE RADICAL; only the 4-x]

8.f(x)= squareroot x^4-16x^2

FIND THE RANGE ONLY [9-12]
9. f(x) 10-x^2
10. g(x)= 5+ squareroot 4-x
11.f(x)= x^2/1-x^2
12. g(x)= 3+x^2/4-x^2


THAT'S ALL; I'LL CHECK BACK ON THIS Q EVERY FEW MINUTES. ASK FOR ANY CLARIFICATIONS IF YOU NEED THEM.
