Definition (Average of Arithmetic Function).

Let be a Arithmetic Function then I define average as

For example for

Theorem (Euler Maclaurin summation Formula).

Let be real numbers and ( . exist and is continuous)
then

where is the fractional part of t

Application

i)

where means something is absolute value .i

for some and Large
Here is known as the Euler Maclaurin constant

complete the madness

proof of E-M

we have

the rest is exercise
decide if you should complete it

Application

We have

Proof.

□

Dirichlet's Hyperbola method

Let be arithmetic function and ,, be positive real numbers such that
then

Proof.

□

Application

Proof.
we have

Hence choosing we have
