Problem:
Find the jacobian of the vector valued function $\begin{pmatrix} f(x,y,z)\\ g(x,y,z) \\ h(x,y,z)\end{pmatrix}$ where $f(x,y,z) = \cos \left(z^3\right)$, $g(x,y,z) = \cos ^{-1}(x)$, and $h(x,y,z) = \sin \left(z^3\right)$
from sympy import *
from sympy.abc import x, y, z

f = cos(z**3)
g = acos(x)
h = sin(z**3)
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
