Inverse trigonometric functions are useful when trying to determine the remaining two angles of a right triangle when the lengths of the sides of the triangle are known.

很多编程语言提供两自变量 atan2 函数，它计算给定 和 的 的反正切，但是值域为 。 在笛卡尔平面上 (紅)和 (綠)函数的常用主值的图像。 下表列出基本的反三角函数。 如果 允许是 复数，则 …

Arc Tangent (atan) is the inverse function of Tangent (tan), which means that a==tan (atan (a)) for every value of 'a' that is within atan ()'s range. This is an online free atan calculator. You can calculate value of atan () trignometric function easily using this tool.

Y = atan(X) returns the Inverse Tangent (tan -1) of the elements of X in radians. The function accepts both real and complex inputs.

In trigonometry, arctan refers to the inverse tangent function. It is usually denoted as arctan x and the formula is θ = arctan (Perpendicular / Base)

Definition of the arctan function in trigonometry. The inverse of the tangent function. The angle whose tangent is a given number.

2024年2月18日 · Arctan (tan-1x) is not similar to 1 / tan x. tan-1 x is the inverse of tan x whereas 1/ tan x is the reciprocal of tan x. tan-1 x is used to solve various trigonometric equations. In this article, we will study the arctan function formula, graph, properties, and others in detail. What is Arctan? What is Arctan Formula? What is Arctan?

2024年9月27日 · 通过使用 ATAN 函数，用户可以将正切值转换为角度值，简化数学计算过程，提升数据分析的准确性和可靠性。 结合其他数学函数，如 SIN 、 COS 、 TAN 、 ACOS， ATAN 可以帮助用户更全面地处理和分析角度和三角关系数据，满足多样化的数据处理需求。

2017年1月14日 · atan stands for "arc tangent." It is the inverse function of tangent - this means it undoes the tangent function. So atan (tan (30)) = 30.

ATAN (x) returns the arc tangent of x. The arc tangent function is the inverse function of the tangent function and calculates the angle for a given tangent x. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function. The argument x can be a real number, a complex number, or a matrix.
