first rotating around the X axis is the latitude value, and then the degree of rotation around the Z axis is the longitude value. The spatial coordinates of A and B are calculated as (x1, y1, z1) and (x2, y2, z2) respectively ). 3. then calculate the angle between the two vectors of the space. The formula is: Cos θ = (OA * OB)/(| OA | * | OB |) = (x1 * x2 + y1 * y2 + z1 * z2)/(r * r) = x1 * x2 + y1 * y2 + z1 * z2 Finally, use arccos to obtain the ang

I did not expect so many limitations on the calculation of latitude and longitude in the J2EE today. Even a few simple trigonometric functions are not completely provided, and I need to write them directly. no way.

latitude and longitude coordinates In actual Web development, there are more and more professional algorithms in some specific fields. For example, the distance calculation method mentioned in this article is based on two dimensions. Two common computations: 1. The distance to be calculated is the elliptical distance. Set the longitude and latitude of the first Vertex A to (LonA, LatA), and the longitude and latitude of the second vertex B to (LonB, LatB) based on the zero-degree longitude line

This is a known distance between two points. Can you see if it is helpful? Hope it will be helpful to you!'----------------------------------------------------------------------'The known longitude and latitude Distance Function'----------------------------------------------------------------------Function countdistance (byval lon1 as double, byval LAT1 as double, byval lon2 as double, byval LAT2 as double) as doubleDim D as doubleDim A1, A2, B1, B2 as doubleA1 = LAT1 * 0.0174532925194A2 = LA

center angle.Since R is determined, the arc AB length can be obtained as long as the angle θ between OA and OB is obtained. Arc AB = R * θ.Angle θ can be obtained through the vector formula: vector OA * vector OB = | OA | OB | cos θ.ThenCos θ = vector OA * vector OB/| OA | OB |= (Ax * Bx + Ay * By + Az * Bz)/R * R 4. Use latitude and longitude coordinates to represent three-dimensional Cartesian coordinates:Ax = R * cosAw * cosAjAy = R * cosAw * sinAjAz = R * sinAw Bx = R * cosBw * cosBjBy = R

1. Differential Application 1.1 Differential 1.1.1 monotonicity, extremum and asymptote of unary functionThe derivative gives the direction of the function, which is very useful for the graphical properties of our analytic functions, and here we use the knowledge of calculus to understand the nature of the function. The effect of the first derivative on the function is the most direct one, where first-order derivative is seen. For the constant function on the interval \ (f (x) =c\), its derivati

-dollar number, and the vector $\mathbf{v}$ is called its imaginary part. If a four-dollar imaginary part is $\mathbf{0}$, it is called the real four-dollar number. Conversely, if its real part is $0$, it is called the virtual four-dollar number. The definition is similar to the plural.A four-dollar number can represent any rotation in a three-dimensional space. Similar to the rotation matrix, we still assume that a rotation is around the unit vector $\mathbf{n}=\left[n_x, n_y, n_z \right]^t$ is

A Jewish elder loves to play golf. On the seventh day, he felt itchy and wanted to swing, but the Jews stipulated that believers had to rest on the seventh day and could not do anything. But the elders finally failed.Stay, decide to secretly go to the golf course, just think about nine holes. No one on the court would ever go out on the day of the day, and no one on the court would have known him to violat

, writing down the planning list means they have no flexibility or autonomy. They think that those who have plans are controlled by their daily plans and there is no room for arbitrary control. These so-called truths are actually irrational.
