'Axis rotation is a rotation about an arbitrary axis by
some angle. The angle is supplied as a SymPy expr scalar, and
the axis is supplied as a Vector.
Parameters
angle : Expr
The angle by which the new system is to be rotated
axis : Vector
The axis around which the rotation has to be performed
Examples
>>> from sympy.vector import CoordSys3D
>>> from sympy import symbols
>>> q1 = symbols(\'q1\')
>>> N = CoordSys3D(\'N\')
>>> from sympy.vector import AxisOrienter
>>> orienter = AxisOrienter(q1, N.i + 2 * N.j)
>>> B = N.orient_new(\'B\', (orienter, ))'
