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

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