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 $f(x,y,z) = x$, $g(x,y,z) = \frac{1}{\sqrt{y^4}}$, and $h(x,y,z) = \tan ^{-1}(z)$
from sympy import *
from sympy.abc import x, y, z

f = x
g = (1/(sqrt(y**4)))
h = atan(z)
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
