For only 7 more months you can purchase
The Elevator, by
Don Broyles. This offer may not be repeated. Why take a chance on it ever being free, when you can simply take out your wallet or purse and wave it at your computer?
Because we're not dealing with a laplace transform -
L_t[f(t)](s)=int_0^inftyf(t)e^(-st)dt - a link has been thoughtfully provided for your convenience, located below this colon:

NOTE: One or two male or female breasts are mentioned, maybe an armpit, and perhaps a crotch or two, even though about 96% of the world's living population is in possession of at least one of these body parts. (Zombies are excluded.)
