So I am able to get to u(x,t) = sum_{n=-infty}^{infty} Cexp(iBx - ktB^2) + Dexp(-iBx - ktB^2) because the general series is sum_{n=-infty}^{infty} X(x)T(t) You have 1 coefficient in your general series, yet I have 2. How do I get it into 1?
Have the following question regarding extracting information from a waveform a. Write down an expression, in the time domain, for the signal in the diagram above. b.Derive the Laplace transform for this signal. c.Use Laplace transform analysis to derive the Fourier transform in its simplest form. All details in the a ...continues
1. Find the Fourier sine series of f(x)=1, 0
Could you please show me how to do the problem attached? You don't have to do the first part (proving solutions to the wave equation by a separation of variables) as I know how to do that. Please start where it asks what is a normal mode, etc... Thank you.
See attachment.....please show each step in detail in the solution.
