I am going through a worked example to calculate v(t) of the capacitor in an RLC circuit. I am questioning the result of \(\frac{dv(0)}{dt}\)=260. Why is it not -260. They have done the same thing with the other 2 cases (not shown).

 

Yes the solution is incorrect

\(v(t)=-0.2083e^{-2t}+5.2083e^{-50t}\)

 

I thought as much. Makes it difficult when your trying to learn and there is errors in the text.
