Document Summary
For each list answer yes or no and explain brie y. You should not have to compute any w(x): {sin(x), x sin(x), {sin(x), sin( x), {sin(x), cos(x + 2), [20 pts] solve (x + y)dx xdy = 0, [15 pts] consider dy y3 . Use ch2 language, such as exact, separable, etc. Show the rst step of the solution (for example, set y = something or = something, etc), to show that you know the usual method, but you do not have to solve it. 2x = x dx + y: [10 pts] consider (5x + 2y + 1)dx + (2x + y + 1)dy = 0. Show the rst step of the solution, but you do not have to solve it. Bonus) [10 pts] solve the ivp, dy dx + y = f (x), where f (x) = (cid:26) 5, 1, if 0 x < 10 if x > 10.
