Document Summary
This should take about 20 minutes, with a lecture afterwards: [40 pts] solve the i. v. p: 2y. X 12y = 0, y(0) = 2, y (0) = 1. Hint: the general solution to the de is c1e4x + c2e 3x. X2 : [30 pts] label each de with its type - exact, separable, homogeneous (as de ned in. 2. 3 to nd (t) (or, if you have forgotten it, you might be able to derive it as we did in class friday): check that converts the linear de into an exact de. Remarks and answers: the average among the top 25 was approx 75/100, which is good. You can use the scale on the syllabus to assign yourself a letter grade, a"s = 85-100, b"s = 75-84, etc. This quiz counts approx 5% of your semester grade: y(x) = e4x + e 3x. This was very similar to the hw from ch. 1. 3.
