Guest pothuri Posted April 18, 2004 Share Posted April 18, 2004 hi can anyone help me solve the integration f(x)=integral[e^(-integral(P(x)dx))/y1(x)^2] thnx Link to comment Share on other sites More sharing options...
NSX Posted April 18, 2004 Share Posted April 18, 2004 that seems a bit too general to me. is there any relation b/t the VAR's of P(x) and y1(x)? Link to comment Share on other sites More sharing options...
Dave Posted April 18, 2004 Share Posted April 18, 2004 If I'm not very much mistaken, that's the formula for the solution to a differential equation using an integrating factor. The integral is very general, there's no specific way of solving it. Link to comment Share on other sites More sharing options...
Guest pothuri Posted April 18, 2004 Share Posted April 18, 2004 hi.... am extremely sorry not mention the functions P(x) & y1(x) the final equation after substitution of P&y1 is f(x)=integral[x^a*e^(-b/x)/(Ax+B)^2] you are right dave i was solving a differential equation and i am stuck here at the integration. thanx Link to comment Share on other sites More sharing options...
dryan Posted April 24, 2004 Share Posted April 24, 2004 I'm not sure, I've only taken Calc I, so I've only done a few differential equations, (only separable ones). You have a lot of variables in there, but the only way I would know how to do it is integration by parts, u=x^a and dv=e^... but that wouldn't help much. I'm not sure you're two equations match, unless you've integrated one of the parts... You had two integrals before? Link to comment Share on other sites More sharing options...
