Solution to Question 7
Fragment of a discussion from Science talk:Math Exam Resources/Courses/MATH102/December 2015/Question 07
Hi Brian and Ziming,
I made some changes to the solution to make it easier to read. Furthermore, I kind of think it's good to have a solution in which the differential equation is explicitly solved instead of just using process of elimination, so I added a second solution. I've changed the tag from QBS to RS.
