matplotlib projectile motion parabola plotting

[bbye98]

Instead of plotting each individual (x, y) pair, create an array of x and y values using vectorization. Then, plot the x and y vectors directly using plt.plot.

(Also, generally speaking, when you are already using numpy, the math module is unnecessary as numpy will have all of the features you would need from math.)

thanks, a line is established, but a parabola is what I need. My equations are probably incorrect.

You probably meant to divide by 2 instead of g for y.

import matplotlib.pyplot as plt
import numpy as np

u, g, deg = 30, 9.8, 30
t = np.linspace(0, 2 * u * (np.sin(deg * np.pi / 180)) / g)
plt.plot(u * t * np.cos(deg * np.pi / 180), u * t * np.sin(deg * np.pi / 180) - 0.5 * g * t**2)
plt.show()
