Aug 23, 2023 at 9:59 comment added Janaka Rodrigo We have lots of applications related to the convergent geometric series but none was available for convergent series of angles. By carefully examining the provided figures with geometry theorems in mind it's not big challenge to realize figures can be used to evaluate the sums of infinite series of angles $$arccot(3) + arccot(7) + arccot(13)+.... $$ and $$arccot(2)+ arccot(8) + arccot(18) + .....$$ and show that the sums equal to$ π/2$.
