Please help with that parametric surface

[BETAPANDERETA]

Please, I want to know or some guide to plot that parametric surface

First one I want to thank you for this content, it's amazing.
Returning with my problem I mean something like this:

I saw that post http://lemur.cmp.uea.ac.uk/Research/ivis/backup/PhD/Latest/Paul%20Bourke%20Screenshots/Eggs,%20melons,%20and%20peanuts%20-%20Cassini%20Oval.htm to guide me, but I can´t understand how can I use that info. to create the parametric surface using ParametricSurface(lambda u, v: np.array([ # The parameters of that surface]))

I'll be very greatful if you can help me.
I'm trying with this

lemnisBer = ParametricSurface(
                lambda u, v: np.array([
                   np.cos(u) / (np.sin(u)**2 + 1),
                   0
                   np.cos(u) * np.sin(u) / (np.sin(u)**2 + 1),
                ]), u_min=TAU, u_max=TAU, checkerboard_colors=[YELLOW_E,YELLOW_E],
                resolution=(15, 32)).scale(1.5)

But that don't graph a peanut or something similar.
Best and sincerely greetings,

Since this is not a question about installation or my tutorials, I recommend that you watch my How to ask your questions about manim video. If you are still interested in me personally solving your question, I would charge you 15 USD via PayPal.

Oh thanks you, I solved that , I did the graph that I want, but I´m very grateful with your tutorial and start guides.
