There are a few elements that are typically included in a research paper cover page:
The title of the paper
The name of the author (or authors)
The name of the institution
The date
Sometimes, additional elements such as acknowledgments or disclaimers might also be included. The important thing is to make sure that all of the required elements are present and that they are formatted according to the instructions given by the professor or journal.
