## Homework Statement

The solutions to the linear differential equation d^2u/dt^2 = u for a vector space. Find two independent solutions, to give a basis for that solution space.

## The Attempt at a Solution

I want to understand this question. I feel that there's something I'm missing. I believe that I need to find the Transformation Matrix, but I need to understand how :(

Any hints or tips are greatly appreciated, but please don't give me just an answer! )
