When writing to argue, persuade and advise, you are offering ideas to other people.
However, each style does this in different ways. If you argue, the writing tends to look at both sides and come to a conclusion. If you persuade, it tends to be one-sided, making your ideas the only sensible choice. If you advise, it tends to be softer, guiding someone towards your ideas.
