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 $f(x,y,z) = \log \left(\frac{x z}{y}\right)$, $g(x,y,z) = \sin \left(\frac{x}{y}\right)$, and $h(x,y,z) = \tan (z)$
from sympy import *
from sympy.abc import x, y, z

f = log(((x*z)/y))
g = sin((x/y))
h = tan(z)
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
