| I have an expression involving subscripted variables, $x_i$ (and constants, $b_k,c_k,d_k$). I would like to compute the Jacobian but the most straightforward application of the D operator, $D[f,x[k]]$ always returns 0. I want to compute... |
| I understand the increased complexity of definite integrals; however, the example I gave is real and non-singular. I am attaching another notebook which illustrates what appears to be a related problem: the integral of a real function over the line... |
