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

f = sin(x-y)
g = acos(y/x)
h = sqrt(z)
X = Matrix([f, g, h]) 
print(X.jacobian((x, y, z)))
