Question 3 pts


(Lesson 3.1: Solving a Differential Equation.) Consider the differential
equation with . What is the exact
formula for ?


a.


b.


c.



This takes a little work. The good news is that you can actually get
the true answer using the technique of separation of variables. We
have




so that




Which implies

,

so that , where and are arbitrary constants.

Setting implies that , so that the exact answer is ,

the answer is , i.e., choice (c).



d.
