A simple rule dictates my buying: Be fearful when others are greedy, and be greedy when others are fearful. And most certainly, fear is now widespread, gripping even seasoned investors. To be sure, investors are right to be wary of highly leveraged entities or businesses in weak competitive positions. But fears regarding the long-term prosperity of the nation's many sound companies make no sense. These businesses will indeed suffer earnings hiccups, as they always have. But most major companies will be setting new profit records 5, 10 and 20 years from now.

IBM’s acquisition of Red Hat is huge news for the Linux world

We are devastated to learn of the tragic passing of a member of our Googler family. On Monday night, our colleague Emily Hong passed away after being struck by a shuttle bus on our Mountain View campus. Emily worked in the finance organization and was beloved by her colleagues -- she brought an incredible spark to Google. She was inquisitive, creative, analytical, positive, generous and kind -- our deepest condolences are with

why ea is committed to the amiga.

As illustrated in below, draw rays from 0 through Z(t) and Z(t+1), together with circular arcs (centred at 0) through those points.

Recovering from our feigned bout of amnesia concerning complex numbers and their geometric interpretation, Cotes' result becomes simple to understand and to prove.

However, not any old mapping qualifies as motion, for we must also capture the idea of the sheet remaining rigid while it moves.
Armed with this precise concept of motion, our final definition of geometric equality becomes...
buf for the moment we wish only to explain how Klein was able to generalize the above ideas so as to embrace such new geometries.
But will this type of equality behave in the way we would like and expect?
If M and N are members of G then so is the composite transformation.
If two transformations do not alter distances, then applying them in succession will not alter distances either.

Pythons kill by tightening their coils so that their victim cannot breathe.
Many private colleges are coining it.
Jaron Lanier coined the term 'virtual reality' and pioneered its early development.
These findings are a reminder that low pay is the other side of the coin of falling unemployment.
Plant them in a coarse, well-draining soil mix with lots of coir and sphagnum moss.

In a full-throated defence of America’s forward-leaning stance abroad, John F. Kerry, US Secretary of State, hit back at critics who have claimed that the United States is disengaging from world affairs. “I want to make it clear that nothing could be further from the truth,” said Kerry.

produce the two segments till they meet at M.
the chord AA' subtends the same angle at every point of the circular arc.

They are just two examples of hapless mathematicians who would have been dismayed to examine the notebooks.
The image f(z) of a point z may be described by its distance |f(z)| from the origin, and the angle arg[f(z)] it makes with the real axis.
This readily comprehensible result is illustrated in below, ignore the shaded disc for the time being.

it would smack of circular reasoning if we were to assume it while following our new approach.

empirically, appeal to the familiar reflection property of the conic sections.

if n is an integer then the branch point is (n - 1), More generally, the same is true for any fraction.
Notice, incidentally, that all three branches display the by now ubiquitous (yet mysterious) preservation of small squares.
Provisionally, we now take S to be the plane with the points of C removed.
the branch cut C is the work of man - the multifunction is oblivious to our desire to dissect it into three functions.

he first studied the transformations that now bear his name, it is fair to say that the rich vein of knowledge which he thereby exposed is still far from being exhausted. For this reason, we shall investigate the transformations in considerably greater depth than is customary.

Check for yourself that the order in which we apply these mappings is immaterial.
the result is true without qualification.
We should explain that this is not generalization for its own sake; soon we will see how this three-dimensional inversion sheds new light on two-dimensional inversion.

If the conformality of an otherwise conformal mapping breaks down at a particular point p, then p is called a critical point of the mapping.

Thus instead of merely saying that f(z) "dies away to zero like (1/(z^2)) as z tends to infinity", we can now say (more precisely) that f(z) has a double root at z = infinity.

From the similarity of the illustrated right triangles with hypotenuses Nz1 and Nz, we immediately deduce that.
