plotting of graphs - mudezda1 - Feb-09-2019 I have an assignment where i have plot two physics equations named them as x and why, The only unkown is the angle, so i made a loop for the possible angles between 0 and 360 import math import numpy import matplotlib.pyplot as plt l= 1.5 m= 2.5 g= 9.81 d= 2.7 k= 9.08 alpha = 0 while (alpha<360): alpha = alpha + 1 angles = math.radians(alpha) x = 1-((2*l)/d)*math.sin(angles) y = ((m*g)/(k*d))*math.tan(angles) plt.plot(x,y) plt.show()My question is how do i plot the two equations without knowing the value of theta? Is there anything wrong with my code?

Also, you don't need to use loops.You need to create arrays of x- and y-values and plot the parametric graph. import numpy as np import matplotlib.pyplot as plt # define your constants here... angles = np.arange(360) / 180 * np.pi # step is one degree x = 1 - ((2 * l) / d) * np.sin(angles) y = ((m * g) / (k * d)) * np.tan(angles) plt.plot(x, y) plt.show() RE: plotting of graphs - mudezda1 - Feb-11-2019 (Feb-10-2019, 04:32 AM)scidam Wrote:I sincerely thank you for your help.(Feb-09-2019, 06:32 PM)mudezda1 Wrote: My question is how do i plot the two equations without knowing the value of theta?I didn't see the value of theta...(Feb-09-2019, 06:32 PM)mudezda1 Wrote: Is there anything wrong with my code?You don't need |
