tan
(x)¶ Compute tangent element-wise.
LAX-backend implementation of
tan()
. Original docstring below.tan(x, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj])
Equivalent to
np.sin(x)/np.cos(x)
element-wise.- Parameters
x (array_like) – Input array.
- Returns
y – The corresponding tangent values. This is a scalar if x is a scalar.
- Return type
Notes
If out is provided, the function writes the result into it, and returns a reference to out. (See Examples)
