Problem:
Find the curl of the vector field $f(x,y,z)\uvec{i} + g(x,y,z)\uvec{j} + h(x,y,z)\uvec{k}$ where $f(x,y,z) = \frac{x^2}{z^4}$, $g(x,y,z) = \sinh ^{-1}\left(\frac{z^2}{y^5}\right)$, and $h(x,y,z) = \sin \left(z^2\right)$
from sympy import *
from sympy.vector import *

C = CoordSys3D('C')
x, y, z = C.x, C.y, C.z
f = ((x**2)/(z**4))
g = asinh((z**2)/(y**5))
h = asinh((z**2)/(y**5))
print(curl(f * C.i + g * C.j + h * C.k))
