Hard to follow or illegible work will count as incorrect: (10 pts) fill in the blank below each question with a word that best addresses the question. Each response is worth 2 points: is the following ode linear or nonlinear, in an autonomous ode. = f (y), any dy dx dy dx. 2xydx + (x2y ln y)dy = 0: what type of ode best describes the fol- lowing equation? a1(x) dy dx. Exam i: childress, (10 pts) solve the following by nding an integrating factor and making the equation exact. ydx (2x + y4)dy = 0. Exam i: childress, (10 pts) find the explicit solution to the following bernoulli ivp: dy dx.
