- Hello;
-
- I am a PhD student at the Communication Sciences Institute of the
- University of Southern California.In my research I had to solve an integral
- equation and learned that a usual approach is to convert that eqn. to an
- "equivalent" differential eqn. and then try to solve that.
- I have sources which does this conversion without giving the details.
- I understand that the procedure is to differentiate on both sides of the
- int. eqn. first, simplify it, then differentiate a second time and substitute
- for the terms recognized from the previous step and so forth..
- The integral equation in question is as follows:
-
- 1
- / sin[c*(t-s)]
- lambda_n * psi_n(t) = P*T/2 * | ------------ * phi_n(s) ds
- / c*(t-s)
- -1
- for |t| <=1
-
- and the related differential equation is given to be:
-
- .. .
- (1-t^2)*f(t)-2*t*f(t)+[mu(c)-c^2*t^2]*f(t)=0 for |t| <=1
-
-
- I tried several times to apply the procedure to end up with the
- diff. eqn. but could not do it.Any help will be greatly appreciated.Please
- respond me at laydin@solar.usc.edu.Thank you...
