Python–Sympy curve . translate()方法
原文:https://www . geesforgeks . org/python-sympy-curve-translate-method/
In Sympy, the function Curve.translate() is used translate the given curve by the given values of x, y. It translates the curve along with both the directions i.e. along x-axis and y-axis.
语法:曲线.平移(x，y)
参数: x: 沿 x 轴的平移值 y: 沿 y 轴的平移值
返回:平移曲线
示例#1:
# import Curve, parameter and interpolate
from sympy.geometry.curve import Curve
from sympy.abc import t
from sympy import interpolate
# using interpolate() and Curve()
C1 = Curve((t, interpolate([1, 4, 9, 16], t)), (t, 0, 1));
print(C1)
# using translate()
C2 = C1.translate(2, 3)
print(C2)
输出:
Curve((t, t**2), (t, 0, 1))
Curve((t + 2, t**2 + 3), (t, 0, 1))
例 2:
# import Curve and parameter
from sympy.geometry.curve import Curve
from sympy.abc import x
# using Curve()
C1 = Curve((x, x), (x, 0, 1));
print(C1)
# using translate()
C2 = C1.translate(1, 2)
print(C2)
输出:
Curve((x, x), (x, 0, 1))
Curve((x + 1, x + 2), (x, 0, 1))
