. The y-axis is a with respect to the G ' angle, and a is used to describe the direction of the device. In a counterclockwise direction, the range of A is [0, 2*pi]Yes:
G ' ^2=gx^2+gy^2
Gy=g ' *cos (A)
Gx=g ' *sin (A)
The
G ' =sqrt (gx^2+gy^2)
A=arccos (gy/g ')
Since the value range of the Arccos function is [0, PI], and A>pi, Gx=g ' *sin (a)
When Gx>=0, A=
angle between the vector R and the x, Y, Z axis, which is AXR,AYR,AZR. Observe the right triangle consisting of R and Rx:cos (AXR) = rx/r, similar to:cos (Ayr) = ry/rcos (AZR) = rz/rFromEquation 1We can push export R = SQRT (rx^2 + ry^2 + rz^2)Through the Arccos () function (the inverse function of the cos ()) we can calculate the desired angle:AXR = Arccos (RX/R)Ayr =
everyone.First, we will introduce the Application Scenario: When we use Microsoft CRM products to create A strong customer relationship management system for our customers, the customer wants to track contact B from Company, there are more relationships between them and the influencing factors of decision-making. For example, an employee has resigned from a company, but he still maintains a close relationship with executives of the company, such as frequent learning about
1. Introduction to the algorithm backgroundThe classification tree (decision tree) is a very common classification method. He is a kind of supervised learning, so-called regulatory learning is simple, that is, given a bunch of samples, each sample has a set of attributes and a category, these categories are predetermined, then by learning to get a classifier, the classifier can give the new object the correct classification. Such machine learning is called supervised learning. Classification is
. Compared with previous works, modern combat 2: Black Pegasus HD (Modern War 2: Black Pegasus) has improved its quality and is no longer like a modern war: in Desert Storm, there are only some simple lines. We can see from the following game that the modern war 2: Black Pegasus images are relatively fine, both the gun model and the building model are true. Modern War 2: Black Pegasus is a first-person shooting game with the subject of modern war. In this game, you will join the U. S. Army and t

In November 5, according to foreign media reports, Google is a safe haven for junior managers and software developers in the recession. However, Google has a high recruitment threshold. First, Google prefers graduates from the Ivy League (consisting of eight well-known universities in the United States). Second, even if the applicant is over 30 years old, google also cares about its GPa (average score points). Third, Google needs people who want to change the world. In addition, even if the appl
