Welcome the the forum!
The first line in Tamil is for Ganesh :-)
---------------------------------
யான் பெற்ற இன்பம் பெறுக இவ்வையகம்.Thanks!
The Tamil quote may be roughly translated as:
"Let the whole world enjoy the joy I was fortunate to receive."
I wanted other folks in a certain Tamil speaking Facebook group also to enjoy Math Is Fun that I discovered and that's why I started my post there with this Tamil line.
I have some questions on the last few terms in an infinite series. The question is very low priority for me. I won't die if I don't know the answer but would love to. Where (i..e, which group here) can I ask this?
Thanks.

Thanks!
]]>Unfortunately, I completed my various courses without really understanding large parts of the subjects I studied. Now that I have time, I flit from subject to subject, this time really trying to understand. At this time, I have no hesitation declaring that the emperor has no clothes [ even if I happen to be the one who is the emperor :-) ]
Here is what I wrote about Math Is Fun yesterday on a Facebook group. The first line in Tamil is for Ganesh :-)

யான் பெற்ற இன்பம் பெறுக இவ்வையகம்.
I stumbled into this site while doing a search (for infinite series). This site seems to be exceptionally well done. (This seems like an understatement, really.)

This proof blew me away:
First, we will call the whole sum "S": S = 1/2 + 1/4 + 1/8 + 1/16 + ...
Next, divide S by 2:S/2 = 1/4 + 1/8 + 1/16 + 1/32 + ...
Now subtract S/2 from S
All the terms from 1/4 onwards cancel out.
And we get:S − S/2 = 1/2
Simplify: S/2 = 1/2
And so:S = 1
You can start at whatever level your are in and have some fun.
---------------------------
I certainly hope to have fun here.
