they only show the results, and not how.
Can anyone show how?
Lookacar and others?
"Notably, Euler directly proved the power series expansions for e and the
inverse tangent function. (Indirect proof via the inverse power series
technique was given by Newton and Leibniz between 1670 and 1680.) His daring
use of power series enabled him to solve the famous Basel problem in 1735 (
he provided a more elaborate argument in 1741):[33]" from wiki
Summation of 1/(n^2) = pi^2/6 |
