at 21:35...you can't get the critically damped solution from overdamped solution by putting exponents equal to zero... general critical solution should be x(t)=exp(-w0*t)*(C1+C2*t) , i.e., you need to have a polynomial of the first degree in time multiplying the exponential function....
Thank you for the explanation!
extremly good
the two terms in critical damping equation cannot be linearly dependent. You have to put t in one of those terms
Thanks
thanks!!!
Congratulations!
whats the textbook ?
