LC Tank - Simulator Demonstration - A Live View of the Details - Simply Put 

Excellent tutorial. Thanks.

great tutorial, thank you.

If I remember correctly, LC Tanks are good for when you need frequencies in the MHz range, where a 555 would simply top out. Especially variable frequencies.

i never knew the difference between sine & cosine, thank you.

Thanks! An excellent follow-up to part one, because a picture is worth a thousand words. What is the link to part three? EDIT: Meaning, the details of how to build the amplification and feedback necessary to sustain the oscillation. If you have not made that video, yet, please make it for a frequency of 60Hz, if that is convenient, because that is the frequency that I need. Please and thank you.
