The document discusses the differences between argumentative and persuasive writing. Argumentative writing aims to convince the reader that the author's argument is valid by presenting facts, evidence, and acknowledging opposing claims, while maintaining a calm tone. Persuasive writing aims to get the reader to agree with the author's opinion by using emotion and only presenting one side of the issue in an aggressive tone without evidence. The document also provides objectives and definitions for argumentative essays, discusses their purpose and components, and identifies language features commonly used.
