Let

The exponent is indeed
- not a typo!
Take the antiderivative of
, denoted by
. This recovers a factor of
in the denominator, which lets us condense it to a single factorial.

Recall the series expansion of sine,

Then with a little algebraic manipulation, we get

Differentiate to recover
.

Finally,
, so our sum is
