Infinite Sums - Global Math Week
1 \leftarrow x
And let’s use this machine compute this strange division problem:
\dfrac {1} {1-x}
This is the very simple polynomial
1
, which looks like this
1-x
, which looks like this, one antidot and one dot.
Do you see any one-antidot-and one-dot pairs in the picture of just
