A differential equations study guide contains all of the formulas students taking calculus or a differential equations class would need to complete specific problems, so students in these classes can use it as a reference when completing homework or studying for an exam. A differential equations study guide is especially helpful for students who have trouble memorizing formulas. Students can pull equations from the guide and put them on index cards to make flashcards with for easier, more convenient studying. These study guides also contain helpful information, such as definitions, so a student should never have to forget a term related to differential equations. These study guides can be in either paper format or laminated and hole punched for binder use, so students can use them in order to best suit their studying habits.
