Differential Equations: Direction Fields

  1. Sep 30, 2007 #1
    (a) Sketch the solution curve that passes through (0,-2) in the direction field for (dy/dx)= 2x + y.

    (b) Sketch the solution curve that passes through (-1,3) in the direction field for (dy/dx)= 2x + y.

    (c) What can you say about the solution in part (b) as x approaches positive infinity? How about when x approaches negative infinity?

    Anik, did you see the "sticky thread"? Homework problems should go the PF forum called "Homework", and you are expected to show some work.
