What is the difference between the following codes?
code1
var=2**2*3
code2
var2=2*2*3
I see no difference. This raises the following question.
Why is the code1 used if we can use code2?

2**2 = 2 power-of 2
2*2 = 2 times....
Change the numbers and you'll see a difference.
So "2 times 2" and "2 to the power 2" are the same.
Double stars ( ** ) are exponentiation.

In mathematics the identity (1 + sqrt(2))^2 = 3 + 2*sqrt(2) holds true. But in floating point (IEEE 754, using single precision i.e. 32 bits) calculations it's not the case, as sqrt(2) doesn't have an exact representation in binary.
So does using a approximated...

To answer another part of your question....
So does using a approximated value of sqrt(2) provide with numbers that require decimal fractions (other than powers of .5 and .2) to represent.
To the exact result of a computation are expected.

What's an elegant way to unify X,Y with (1,2), (1,-2), (-1,2), (-1,-2), (2,1), (2,-1) , (-2,1), (-2,-1)?
Doing it this way seems error prone and tedious:
foo(1,2). foo(1,-2). foo(-1,-2). ... ... ...
And this way seems too expensive:
foo(X,Y) :- L = [1...

Foo(X.
Foo(X, Y) :- foo(-X, Y).
Foo(2, 1).
Foo(1, 2).
Foo(X,Y):- foo0(X,Y); foo0(Y,X).
A further development on what was commented:
generate_pairs_foo(X,Y) :- L = [1,-1,2,-2], member(X,L]), member(Y,[2,-2]).

Rarely do I have the room for CED.
I run 2 Sw 2 CED and 1 BTH 2 of each and BTH.
Why not 2 SW and 1 of each of the others? 2 Solemn and 2 CED.

What are the critical points to (f prime) = (-x^2 + 2)/(x^2 - 3) and (f prime) = (-x^2 + 2)/(x^2 - 3)^2?

Answer Snippets (Read the full thread at yahoo):
For critical point dy/dx=0
dy/dx= (x^2-3)(-2x)-(-x^2+2)(2x)
=0
(x^2_3)^2
2x[3-x^2+x^2-2]=0
2x=0
x=0 so y=2/3 critical point (0,2/3)
dy/dx=(x^2-3)^2(-2x)- (-x^2+2)*2(x^2-3)(2x).

For the first part of your question, you can either use... .
Re: the first part, you can filter out the rows with Frequency == 0 by
filteredRows <- data$Frequency != 0 ## restrict ourselves to looking at the data where Frequency != 0 .
