I suppose you mean to have a third variable, z, in that expression? If so then you should be able to follow the same reasoning starting at 17:15 in the video. The surface won't be a sphere, but something similar. I recommend looking at how it intersects the coordinate planes (xy-plane, yz-plane, and xz-plane). You can do that by setting one variable equal to zero and looking at the curve defined by the remaining two variables.
If you mean the values of c we chose here, there's no restriction on what those might be in general But, for specific problems, some values will be more appropriate than others. You will need to rely on your intuition and experience to choose the best values of c. Sometimes it's just trial and error.
In 20 minutes you taught me more than my professors did.
bro this is amazing u have a deep understanding of the concept
ty
Please continue your teaching it's not what others able to teach. Exceptional especiallly the saftware explanations thanks a lot
Glad you found it helpful!
Your explanations leave nothing out. You answer questions before they get asked. Thanks 👍
Wow , you explain so good, can see that you have put lot of efforts in making these videos . Kudos , thanksss
brother you saved you from this nightmare
This is insanely cool
This is so helpful thank you very much!!!!
wow sersly awesome what my prof cant teach me in 1 hours you did it in just 6 mins
thank you for this! very educational 🙌
sir please continue and upload more tutorial
Thanks, super helpfull.
Please show us how to draw a level surface for ln(16 - 4x^2 - y^2 - 4x^2)

Hello, can I contact you? If you have a telegram or any communication site.
Best to just leave a comment here. If I have time I will try to respond.
