Solving Initial Value Problems
with Mathematica's Solver

Solve each of the following initial value problems using Mathematica.

  1. y″ - 6y′ + 9y = xe3x, y(0) = 1, y′(0) = 0

  2. y″ + 25y = cos(5x), y(0) = 0, y′(0) = 0

  3. y″ + 3y′ + 2y = sin(ex), y(0) = 0, y′(0) = 0

  4. 4y″ - 4y′ + y = ex/2(1 - x2)1/2, y(0) = 0, y′(0) = 0
