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 $f(x,y,z) = \tan (x z)$, $g(x,y,z) = \cos (x-y)$, and $h(x,y,z) = \frac{1}{z^{3/2}}$
from sympy import *
from sympy.abc import x, y, z

f = tan(x*z)
g = cos(x-y)
h = (1/(z**(3/2)))
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
