No, coth is a trigonometric function with no real existence and so cannot be eaten.
If A activates Call of the Haunted and B Chains Mistical Space Typhoon, COTH is destroyed and no monsters are summoned. If COTH is chained to MST, either monster will be summoned, but then MST will destroy COTH, and the monster will also be destroyed. However, either monsters effect will activate as both will be summoned then destroyed.
Rewrite it as cosh/sinh
Yes, you can use the effect of "Swarm of Scarabs" after reviving it with "Premature Burial" or "Call of the Haunted" ("CotH"). If "Premature Burial" was used on "Swarm of Scarabs", then "Premature Burial" will be destroyed and sent to the Graveyard since Spells cannot be equipped to a face-down monster. If "CotH" was used instead, "CotH" will simply stay on the field. It is no longer "connected" to "Swarm of Scarabs". And essentially serves no function. In both cases, "Swarm of Scarabs" is independent of the card used to revive them. It will not be destroyed in the card used to revive them is destroyed.
