Here's a list of wiki articles I've contributed to on Brilliant
Now I didn't write all these articles all by myself. Many members of the community also contributed to them and made them as they are today. So if you see an article you can help improve, by all means do that! I'll keep updating this list as I contribute to more and more wikis on Brilliant.
I look forward to update the infinite sums wiki so as to cover all topics including Double, Triple Summations, Summations using Definite Integral and all that.
Also, coming next are, wikis on Hockey Stick Identity, Beta Function, Poygamma Function, Mathematical Cornucopia, and a another kind of expansion which I found recently.
And please do give your suggestions. All kinds of feedbacks are appreciated.
