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 $f(x,y,z) = \frac{1}{x}$, $g(x,y,z) = \frac{1}{\sqrt{y}}$, and $h(x,y,z) = \frac{y}{z}$
from sympy import *
from sympy.abc import x, y, z

f = (1/x)
g = (1/(sqrt(y)))
h = (y/z)
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
