在ANSYS仿真中经常会遇到一些动态的加载方法,加载的载荷(位移、力、电流、温度等)随着时间而变化,表示不同的状态。而相应的在workbench中可以方便的采用表格方法设置不同时间状态下加载的位移或受力等载荷。但是又实用需要APDL命令的方式书写不同时刻的载荷,但是函数库当中又没有相应的函数,那么如何书写呢,下面我们选取...
It is similar to calculating the arc tangent of y / x, except that the signs of both arguments are used to determine the quadrant of the result. The function returns the result in radians, which is between -PI and PI (inclusive). func Atanh func Atanh(arg float64) float64 Atanh - ...

In the Petzold.Astronomy library, I try to avoid confusion and conversions between degrees and radians by implementing a struct named Angle. You can create an Angle value from either a degree or a radian using the static FromDegree or FromRadian methods, and get the degrees or radians out, ...

zero as the phone is turned facedown. Pitch ranges from –π to π with the maximum values when the phone is facedown. With the phone’s screen facing up, yaw should be more or less the same value as the TrueHeading property from the Compass, but converted to radians for XNA purposes...
