I am currently studying differential equation now, and I just have one question about the symbolic expression for an initial value problem. I don't quite understand what does sympolic expression mean, any explanation or help would be really appreciated.

  • $\begingroup$ I assume it means writing $x$ as a function of $t$? What do you think it means? $\endgroup$

  • $\begingroup$ The word should be "symbolic". The "p" is a typo. What they want is for you to write $x = Qe^{At}$, for some $Q$ and then find the value of $Q$ that will give $x(0) = [-1, 3]^T$. $\endgroup$ Dec 5 '17 at 3:19
