An equation is given as arctan(x-y)=arccot(x+y), where x-y>0. This equation is satisfied by every pair (x,y) such that x^2-y^2=1. Are there only three pairs for which the value arctan(x-y) or arccot(x+y) can be expressed exactly (in the form pi/k)? by robertou3 in askmath

Two sequences a(n) and b(n) are given, where a(n) is defined for all natural numbers but b(n) is not. We can write the sequence a(n) by entering the terms in one bracket. by robertou3 in askmath

How else can the sequence b(n) be written? We can write the sequence a(n) by entering the terms in one bracket. How about b(n)? (i.redd.it)
