我想用参数化制作一个曲线动画(在其中递增绘制):x(t)= sin(3t)和y(y)= sin(4t),其中t [0,2pi]。
尝试:
%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'对象不是可迭代的...我该如何解决?
谢谢
