## Re: ODE Problem

There's probably an easier way to do this, but one valid and straightforward method is to convert to the system

,

where . We use this to find the fundamental matrix

and determine for some constants . It's easy to verify that the solution to the IVP in (i) is then given by .

## Re: ODE Problem

Hi. Thanks for the reply

I should have been more specific sorry. its part ii) that Im really stuck with. sorry

for part i) I put the values into the quadratic formula and then with the obtained values substituted them into general solution giving me the desired graph that i was looking for

If you could help me with part ii) that would be great.

thanks
