Quantcast
I want to understand this connection better.
Although it sounds the most involved, arctan answers the simplest trigonometric question you could ask. “The full moon subtends seven degrees of my vision; so how big is the moon?” The arctan (with radius = distance from Earth to moon) is the answer.
But what does that simple operation have to do with:
a continuous sum of
an inversion of
one more than
some sequence of numbers
times themselves?
That’s confusing.
