Ethos, Pathos & Logos are very important in writing in order to convince audience. Ethos is basically the source's credibility or the author's authority. It is often conveyed through tone and style of the message and through the way the author refers to differing views. Pathos means persuading by appealing to the reader's emotions. Lastly, logos is just about logic, they can be the facts and statistics that are used to help support the arguments.
