I was working on a problem in which you were given three points, (0,2) , (2,3) ,and (4,5) which lie on the circumference of a circle and you had to find t in the point (0,t). the three points give you two chords. The perpendicular bisectors of the two chords give you the center of the circle which gives you the radius from which you can calculate the t in (0,t). Anyway, the reason for this note is that I accidentally hit something on my keyboard and lost the problem and now I can't find it. This has happened to me before. Is there documentation explaining how to navigate the site?

TopNewestFirstly you can go and check "Started Problems" in the menu at the top right hand corner. You will find the problem there.

Secondly you can check this for help.

Thirdly if you have any query you need not write a note. You can directly ask your query here. – Sudeep Salgia · 2 years ago

Thanks Calvin. Again, that's just what I was looking for. – Michael Enright · 2 years ago

In this case, since you remember the question well enough, you can use the search functionality. For example, searching just for "(0,2) , (2,3) ,and (4,5)" gives:

The problem that you want is the 3rd item (and this note is the 2nd).

You can also use the filter functionality on search, to restrict it to just problems. – Calvin Lin Staff · 2 years ago
