I recently finished an assignment to visualise the lagrangian of a simple pendulum by plotting the odeint solution along with the hands-on mathematical solution of the second degree diff equation. I loved the way you put the animations. I'm gonna try it as well!
wow this is amazing, I recently undertook a long project for my degree based entirely on numerically integrating the 3 body problem, finding this out now makes me wonder how much time I could have saved just using sympy. Thanks so much for this content!
I was trying to compute kinetic energy by lambdifying the expression for T (getting T_f). I got no error when I did the lambdification, but when I invoked T_f with the appropriate parameters I got the error name 'Derivative' is not defined. What to do?
Very nice work! Congrats! I don't know if you've been through this but I'm having the following error when calling the lambdify method: deriv2_f = smp.lambdify((g, the, the_d), deriv_2) File "", line 1 lambda _Dummy_168,_Dummy_169,Derivative(\theta(t), t): (0.25*(-_Dummy_168 + 4.0*Derivative(_Dummy_169, t)**2)*tan(_Dummy_169)) ^ SyntaxError: invalid syntax
You know you are doing awesome things on youtube, but it's hurting me so bad that you could not get the same amount of views that one would get with the shity stuff they are doing.
I cant explain how much I appreciate this channel. It's making me a better physicist and you make it look so cool
Cheers :D
Very much agreed.

Damn boy. Keep up the good work!
Will do sir!
Best channel on physics, engineering and python! A real treasure trove.
Thanks for your videos! Although I am now retired, I am just having fun working physics problems, and your videos are incredibly helpful.
Awesome! I love the animations! Definitely hope to do animations too myself. As always, great content.
Looking forward to your 1K and 1M subs videos
Saving the trees with SymPy :D
Quality at its maximum. Thx.
You are amazing! I love this
Fuck paper
New subscriber here, appreciate a lot your videos (already in the discord channel) keep going
Excellent video
At 8:30, the order of the terms are not keeped, the m and the g are inverted.
Is there a way to avoid this ?
Thanks for yours video. Very very useful.
I like the video so much.
how would you go about plotting theta dot vs theta inorder to obtain the phase space of these motions?
Amazing video
Thank you for your video. How can we use other numerical solvers such as RK45, ODE45 , besides odeint. can you please give us some recommendation?
Help me, please. Instead of showing a proper d(theta)dt, it shows Derivative(\theta(t), t) instead.
great video, how would i add a dissipation function?
Wonderful
How do you get output in beautiful LATEX form? It doesn't happen when I do it.

how did you learn to to do that?!!
I want to do that too!
Very nice work! Congrats!

Can you please post the code?
I've updated the video description and posted a link
@@MrPSolver Thank you man, you are amazing!
What about an absolut() curve pendelum? Something about the derivative from math
I wondered during continuum mechanics if particles were used as random init matrices for a calculated path through difficulties //Per
