@yuvrajsingh Sorry to move messages, but I like to keep things on-topic. By the way, you should explain what you know and what you've tried otherwise you can't improve your problem-solving skills.

@MartinSleziak Lol seems like they don't work here.

@user21820 sinpi/7sin3pi/7+sin3pi/7sin5pi/7+sin5pi/7sinpi/7
=f(cospi/7), where f(x)=ax^2+bx+c

@user21820 i divide and multiple lhs by 1/2

@user21820 to convert them all to cos(A+B)-cos(A-B)

@user21820 after solving i reach cos(pi/7)=f(cospi/7)

@user21820 Yes - that§s what I was testing. They still work in comments. meta.stackexchange.com/questions/92060/… meta.stackexchange.com/tags/magic-links/info

Does [faq] and [tour] work in comments? Here: faq and tour. — Martin Sleziak 2 days ago

@Hanno As far as I can tell, both [faq] and [tour] are one of the magic links and they work in comments without the need to use [text](url) format: faq and tour. (There is a minor advantage to keeping the comment template a bit shorter - if possible; it's useful in cases when the commenter wants to add something more to the copied template text.) — Martin Sleziak 2 days ago
