Prof. S. Brick Differential Equations; Quiz 1 Math 238

Spring ’08 section 102

  1. Print your name:
  2. Show that y = ex^ cos(x) is a solution to y′′^ − 2 y′^ + 2y = 0.
  3. Verify that y = Ce−x^ + x − 1, where C is a constant is a solution to y′^ = x − y. Then find C such that the initial condition y(0) = 10 is satisfied.
