1. [10/16 Points] PREVIOUS ANSWERS In this question, you Will solve the differential equation % : e7>'tZ 7 497V. This differential equation is separable, in other words, we can write it in the form %{L : p(t) q(y). What aie the two functions p(t) and g(y)7 pm: [974) e? :10) = 97-" J Now separate the variables. Integrate both sides of the resulting equation With respect to t and replace 310% by dy in the integral on the left side. dt f [7," I," :f (,2 7 4) (If W J Do the integrations on both sides. Use k to stand for your constant of integration for the left side and K to stand for your constant of integration for the right side. [Lower case it on left side, upper case Kori right side.) Integrating left side gives Integrating right side gives: 7 7 .11 + k X We can combine the two constants of integration into a single constant, C, that appears as +6 on the right side of our equation. (We do this by subtracting k fiorn both sides of the equation ) Write the new constant C in terms of k and K c: r+(K7k) X Note: For the rest of this problem and for all problems following in this assignment, whenever we do separation of variables, we will use a single constant of integration, adding Cto the right side. Even if it is possible to simplify (like, for instance, when we wroleA : e': in an example in class), you should leave your answer in terms of C. Finally, rearrange to get y as a function of I (The constant of integration, C, will appear in youi answer) y: r+(K7k)+C Submii Answer 2.
