Can the following differential equation be solved without knowing how to solve a second order differential equation? $\frac{d^2 \vec r}{dt^2}-4\frac{d \vec r}{dt}-5 \vec r=0$

2. Haseeb96

Where is the equation?

It is there in my post

5. anonymous

I'll write it again

6. anonymous

$\frac{d^2 \vec r}{dt^2}-4\frac{d \vec r}{dt}-5 \vec r=0$

7. Haseeb96

this is not equation . this is statement.

8. Haseeb96

what is vector r equation here?

9. anonymous

It's a function of t

10. anonymous

That's really all the information that is given

$\vec r(t)=x(t)i+y(t)j+z(t)k$
