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 $f(x,y,z) = \sinh \left(x z^3\right)$, $g(x,y,z) = \cos (y)$, and $h(x,y,z) = \sqrt{z^3}$
from sympy import *
from sympy.abc import x, y, z

f = sinh(x*z**3)
g = cos(y)
h = sqrt(z**3)
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
