示例1: test_requires_partial
def test_requires_partial():
x, y, z, t, nu = symbols('x y z t nu')
n = symbols('n', integer=True)
f = x * y
assert requires_partial(Derivative(f, x)) is True
assert requires_partial(Derivative(f, y)) is True
## integrating out one of the variables
assert requires_partial(Derivative(Integral(exp(-x * y), (x, 0, oo)), y, evaluate=False)) is False
## bessel function with smooth parameter
f = besselj(nu, x)
assert requires_partial(Derivative(f, x)) is True
assert requires_partial(Derivative(f, nu)) is True
## bessel function with integer parameter
f = besselj(n, x)
assert requires_partial(Derivative(f, x)) is False
# this is not really valid (differentiating with respect to an integer)
# but there's no reason to use the partial derivative symbol there. make
# sure we don't throw an exception here, though
assert requires_partial(Derivative(f, n)) is False
## bell polynomial
f = bell(n, x)
assert requires_partial(Derivative(f, x)) is False
# again, invalid
assert requires_partial(Derivative(f, n)) is False
## legendre polynomial
f = legendre(0, x)
assert requires_partial(Derivative(f, x)) is False

assert requires_partial(Derivative(f, x)) is False
# again, invalid
assert requires_partial(Derivative(f, n)) is False
f = x ** n
assert requires_partial(Derivative(f, x)) is False
assert requires_partial(Derivative(Integral((x*y) ** n * exp(-x * y), (x, 0, oo)), y, evaluate=False)) is False
# parametric equation
f = (exp(t), cos(t))
g = sum(f)
assert requires_partial(Derivative(g, t)) is False
