Hi,
I was wondering whether anyone could tell me how to deal with this manipulation, which I am unable to see.
a_1=\frac{F}{(-m_1\omega^2+K_1+K_3)-K_3a_2}
a_2= \frac{K_3a_1}{(-m_2\omega^2 +K_2+K_3)}
Starting with a_1...
Hi,
I am trying to follow an introductory problem in my book for which no solutions are provided and have got stuck. I was wondering whether anyone could tell me how to go about this problem and where I am going wrong.
The problem starts:
Consider the eqquations:
y_1= x_1+2x_2...
Thanks for the hints Silversonic. I will go back through it again but I think I can see how this works out now!
(I just changed the limits because I though it wasn't necessary to integrate beyond \frac{T}{2} because the function there is zero.)
I have been trying to follow how the complex Fourier coefficients are obtained; the reference I am using is at www.thefouriertransform.com. However I am unable to follow the author's working exactly and wondered if anyone could help me see where I am going wrong.
First, I understand that the...
Thanks a lot, Mark... I am getting closer but have one problem. Having done it several times over, the same thing keeps happening:
Using the product rule (uv)' = u'v + uv' I get one extra term.
I'll type it piece by piece for clarity:
\frac{\partial}{\partial u}( u \frac{\partial...
I am not quite sure how \frac{\partial}{\partial u}\left(\frac{\partial z}{\partial u}\right)
=\frac{\partial}{\partial u}\left( u \frac{\partial z}{\partial x}+v\frac{\partial z}{\partial y} \right)
comes to \frac{\partial z}{\partial x} + u\frac{\partial}{\partial u}\left(\frac{\partial...
