+=====================================================
+taylor_expansions (:mod:`clifford.taylor_expansions`)
+=====================================================
+
+.. versionadded:: 1.4.0
+
+This file implements various Taylor expansions for useful functions of multivectors.
+For some algebra signatures there may exist closed forms of these functions which would likely be faster
+and more accurate. Nonetheless, having pre-written taylor expansions for the general case is useful.
+
+.. note::
+    Many of these functions are also exposed as :class:`~clifford.MultiVector` methods,
+    such as :meth:`clifford.MultiVector.sin`. This means that ``mv.sin()`` or even ``np.sin(mv)`` can be used
+    as a convenient interface to functions in this module, without having to import it directly.
+
+    For example::
+
+    >>> from clifford.g3 import *
+    >>> import numpy as np
+    >>> np.sin(np.pi*e12/4)
+    (0.86867^e12)
