OS/X 10.4 Deleting unwanted applications

What is the correct way to delete unwanted applications from a MACbook
running OS/X 10.4.1.1.
It is sufficient to drag and drop from Applications folder to Trash, then clear
Trash?

Depends on the app. If it is self contained then yes, simply trashing it works fine. If the app stores files and resources outside of its own folder, like in /Library, then you would have to use an uninstaller script or perhaps manually trash all those files.

Thanks. I'll check each package.
