So, it follows, by re-writing and telescoping, we have:

Sum to infinity

Now, take , so that for we have meaning that our sum is:

Hyperbolic sum

Write the hyperbolic sum in exponential form:

So take and use the previous result, noting that we have:

Now, for the final result, it's simply double the sum and adding on to account for the term. This cleans up to
