The past few modules introduced various ways to solve a differential equation, separation of variables, integrating factor, and exact equations. As you can see, you need skills from previous coursework, in particular algebraic manipulation and both differentiation and integration, to solve these equations. How do these skills translate to differential equations? In a general sense, explain how algebra, differentiation, and integration skills are necessary to classify and solve first-order ODEs. Include an example in your explanation.
