【解析】 In the solution we will use the subtraction formula for the tangent $$ \tan ( a - b ) = \frac { \tan a - \tan b } { 1 + \tan a \cdot \tan b } $$ $$ w h i c h g i v e s t h e f o r m u l a f o r t h e a r c t a n ...

Then we can also find the prefix sums for all possible arguments of the Dirichlet inverse f−1(n)f−1(n) in O(n2/3)O(n2/3). Proof: Let F−1(n)F−1(n) be the prefix sum of f−1(n)f−1(n) up to nn. The hyperbola formula allows us to compute F−1(n)F...
