| First-Order: Intervals of Validity | Paul's On-Line Notes on the theory of first-order equations. Intervals of validity are what we call intervals of definition. These arise in all of the examples. He first covers the theory for linear equations. (We did this earlier in our notes.) He then covers a general theory for first-order equations similar to the one in this chapter. He does not present the theory for separable equations that is covered in our previous chapter. |
