[英]How to Get the X and Y Positions of All Curves in a Lissajous Curve Table?
[英]How to make an animation of a Lissajous curve
我想用參數化制作曲線的動畫(在其中遞增繪制):x(t)= sin(3t)和y(y)= sin(4t),其中t [0,2pi]。
嘗試:
%matplotlib notebook
import matplotlib.pyplot as plt
import math
import numpy as np
# set the minimum potential
rm = math.pow(2, 1 / 6)
t = np.linspace(-10, 10, 1000, endpoint = False)
x = []
y = []
for i in len(t): #TypeError 'int' object is not iterable
x_i = np.sin( 3 * t[i] )
y_i = np.sin( 4 * t[i] )
x.append(x_i)
y.append(y_i)
# plot the graph
plt.plot(x,y)
# set the title
plt.title('Plot sin(4t) Vs sin(3t)')
# set the labels of the graph
plt.xlabel('sin(3t)')
plt.ylabel('sin(4t)')
# display the graph
plt.show()
但是TypeError'int'對象不是可迭代的...我該如何解決?
謝謝
