atan2(y, x) returns the angle θ between the positive x-axis and the ray from the origin to the point (x, y), confined to (−π, π].Graph of (,) over /. In computing and mathematics, the function atan2 is the 2-argument arctangent.

A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
Similarly to Lyman-alpha, the K-alpha emission is composed of two spectral lines, K-alpha 1 (Kα 1) and K-alpha 2 (Kα 2). [6] The K-alpha 1 emission is slightly higher in energy (and, thus, has a lower wavelength) than the K-alpha 2 emission. For all elements, the ratio of the intensities of K-alpha 1 and K-alpha 2 is very close to 2:1. [7]

In engineering problems, especially in the area of solar energy application, the solar azimuth angle, which can be computed from the x- and y-component of the vector pointing to the Sun using the atan2 function, normally measures from due North (positive y-axis) or due South (negative y-axis), this can be achieved by using atan2(x, y) or atan2 ...
