示例1: test_curve
# 需要导入模块: from sympy import C [as 别名]
# 或者: from sympy.C import arbitrary_point [as 别名]

s = Symbol("s")
z = Symbol("z")
# this curve is independent of the indicated parameter
C = Curve([2 * s, s ** 2], (z, 0, 2))
assert C.parameter == z
assert C.functions == (2 * s, s ** 2)
assert C.arbitrary_point() == Point(2 * s, s ** 2)
assert C.arbitrary_point(z) == Point(2 * s, s ** 2)
# this is how it is normally used
C = Curve([2 * s, s ** 2], (s, 0, 2))
assert C.parameter == s
assert C.functions == (2 * s, s ** 2)
t = Symbol("t")
assert C.arbitrary_point() != Point(2 * t, t ** 2) # the t returned as assumptions
t = Symbol("t", real=True) # now t has the same assumptions so the test passes
