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

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