(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Solve du/dt=Pu when P is a projection.

[1/2 1/2 = du/dt with

1/2 1/2]

[5 = u(0).

3]

Part of u(0) increases exponentially while the nullspace part stays fixed.

2. Relevant equations

du/dt = Au with u=u(0) at t=0

3. The attempt at a solution

I'm stuck with this problem. I was thinking that u(t)=e^{λt}*x.

Would du/dt be considered matrix A??? Thanks!
