Ah, thanks for highlighting that Muhammed. Unfortunately, RUclips no longer allows video annotations so hopefully viewers will see your comment. I'll mention it in the video description.
6:33 I spent half an hour trying to fix my code, going to Stack Overflow, downloading these various packages, only to find out I had "npl" instead of "mpl" . 😀😄😆🤣🌚
Hey, I had a problem with the del symbol where it gave me an "invalid character in identifier" error. Am I using the wrong symbol, or is it something with my code? This is the symbol i was using: ∂ My code: import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import axes3d import numpy %matplotlib inline x = numpy.arange(-8, 8, 0.1) y = numpy.arange(-8, 8, 0.1) x, y = numpy.meshgrid(x, y) z = x ** 2 + y ** 2 gradient = [∂z / ∂x, ∂z / ∂y] gradient = [2x + y ** 2, x ** 2 + 2y] axes = plt.axes(projection='3d') axes.plot_surface(x, y, z) # derivative = 2 * x # plt.plot(x, y, x, z) # plt.show
Hi there, Thanks for tuning in! You can get rid of the line with the dels in it. It was for the purpose of explaining the concept, but you don’t need it in your code. All the best, Reuben
Keep getting syntax errors. Already threw out the the bit of code with the ∂ sign. Code seems identical and does not want to run :/.. Keeps saying the opening bracket after gradient = is not closed, but IT IS? import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D %matplotlib inline x = numpy.arange(-8,8,0.1) y = numpy.arange(-8,8,0.1) x, y = numpy.meshgrid(x, y) z = x ** 2 + y ** 2 gradient = [2x, 2y] axes = plt.axes(projection='3d') axes.plot_surface(x, y, z)

I think there is a mistake in 11:03, the partial derivative is wrong it should be like that [2x , 2y], after all thank you for your efforts.

im lost what do i do instead

Really great video, keep up the good work :D
Hello, you should include links to the previously related videos. Thx.
Good idea. Done!
Before the video started I saw an ad with a terrifying looking A.I. for kids, how do they enjoy these? lol
when we made the 3d graph, mine went up in 2.5 instead of 2, do you know why? it only happend on the x and z axes
same :(

import matplotlib.pyplot as plt

%matplotlib inline
x = numpy.arange(-8,8,0.1)
y = numpy.arange(-8,8,0.1)
x, y = numpy.meshgrid(x, y)
z = x ** 2 + y ** 2
gradient = [2x, 2y]
axes = plt.axes(projection='3d')
axes.plot_surface(x, y, z)
im having the same exact problem
