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 $f(x,y,z) = \tan \left(x+y^3\right)$, $g(x,y,z) = \log \left(y^3 z\right)$, and $h(x,y,z) = x^3$
from sympy import *
from sympy.abc import x, y, z

f = tan(x+y**3)
g = log(y**3*z)
h = x**3
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
