'Define the angular acceleration Vector in a ReferenceFrame.
Defines the angular acceleration of this ReferenceFrame, in another.
Angular acceleration can be defined with respect to multiple different
ReferenceFrames. Care must be taken to not create loops which are
inconsistent.
Parameters
otherframe : ReferenceFrame
A ReferenceFrame to define the angular acceleration in
value : Vector
The Vector representing angular acceleration
Examples
>>> from sympy.physics.vector import ReferenceFrame, Vector
>>> N = ReferenceFrame(\'N\')
>>> A = ReferenceFrame(\'A\')
>>> V = 10 * N.x
>>> A.set_ang_acc(N, V)
>>> A.ang_acc_in(N)
10*N.x'

def set_ang_acc(self, otherframe, value):

    if (value == 0):
        value = Vector(0)
    value = _check_vector(value)
    _check_frame(otherframe)
    self._ang_acc_dict.update({otherframe: value})
    otherframe._ang_acc_dict.update({self: (- value)})
