Atan2(x y)
WebThe four-quadrant inverse tangent, atan2(Y,X), returns values in the closed interval [–π, π] based on the values of Y and X, as shown in the graphic. In contrast, atan(Y/X) returns results that are limited to the interval [–π/2, … Webatan2是什么tanθtan \thetatanθ我们首先来看 tanθ=y/xtan \theta= y/xtanθ=y/x :当 (x,y)(x, y)(x,y) 在第一象限，0< \theta < {\frac {\pi}2}0

In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, $${\displaystyle \theta =\operatorname {atan2} (y,x)}$$ is the angle measure (in radians, with $${\displaystyle -\pi <\theta \leq \pi }$$) between the positive $${\displaystyle x}$$-axis and the ray from the origin to the point See more The ordinary single-argument arctangent function only returns angle measures in the interval $${\displaystyle {\left[-{\tfrac {1}{2}}\pi ,+{\tfrac {1}{2}}\pi \right]},}$$ and when invoking it to find the angle measure between the x-axis … See more As the function atan2 is a function of two variables, it has two partial derivatives. At points where these derivatives exist, atan2 is, except for a constant, equal to arctan(y/x). Hence … See more The $${\displaystyle \mathrm {atan2} }$$ function was originally designed for the convention in pure mathematics that can be termed east-counterclockwise. In practical applications, however, the north-clockwise and south-clockwise conventions are … See more • hypot See more The function atan2 computes the principal value of the argument function applied to the complex number x + i y. That is, atan2(y, x) = Pr arg(x + i y) = Arg(x + i y). The argument could be changed by an arbitrary multiple of 2π (corresponding to a complete turn … See more Sums of $${\displaystyle \operatorname {atan2} }$$ may be collapsed into a single operation according to the following identity ...provided that The proof involves … See more The realization of the function differs from one computer language to another: • In Microsoft Excel, OpenOffice.org Calc, LibreOffice Calc, Google Spreadsheets, iWork Numbers, … See more Websudo rosdep init和rosdep update出现的问题. 本文参考公众号鱼香ROS，详情可以参考微信公众号。 我们在安装ROS的过程中都会遇到rosdep初始化失败的问题，刚入门就让劝退选手。
