Laplace/Fourier Transforms; problem from Greenberg Text (scanned)
The problem is number 8 on page 989 of the 2nd Edition of Greenberg's Advanced Engineering Mathematics book, PART C ONLY. This is in section 18.4 (Chapter 18 is the Diffusion Equation), in the exercises at the end of the section. PLEASE NOTE: I have scanned the book pages containing this problem. I only need part C. The solu ...continues
Yinon, If you do not wish to work on the Laplace diffusion problem anymore, I would like to see the solution you have formulated thus far and will pay you some credits even though it is not entirely correct. Please leave me a note. Thank you!
A function h (x) is positive or zero for all values of x. Assume h(x) is even .If the Fourier transformation of h(x) is H(u) show that... (See attachment for full question)
A signal function f(t) of period 2 pi is given by: (See attached file) As required by my question I have drawn the above signal in the interval -4pi < t < 4pi which I beleive to be a sawtooth signal. I also need to find if f(t) is odd, even or neither, hence state which coefficients, if any, are zero. If ther ...continues

Here, we have to find f(t) from the given value of Cn. I'm not able to arrive at f(t)={3/[5-4cos(pit+pi/20)} despite many attempts. Really don't know what went wrong, please show me how to arrive at the final expected f(t) value.
I have tried working and this question and arrived at Cn = 0.5{[1-exp(-4)]/[2-inpi]}. Not sure if it's correct. Find the complex Fourier series coefficients for the function x(t) depicted in the below figure... Please see attached.
