Is it possible to do Feynman path integrals in wolfram alpha? Say for a free quantum mechanical particle. The reason I am interested in this is because I would like to see how it arrives at the solution. I have struggled to understand what a path integral is for a few years now and how to actually compute a simple one. I am not even saying I don't understand it in some intellectual way as to vet its rigor or whatever. I honestly am a smart guy who can't figure out what it is. The big D[x] looking thing always mystifies the whole thing and throws me off. I have managed to sit through its derivation in a Quantum mechanics course but the way it is done in those courses has generally eluded me. I have also attempted to pick up a mathematics book to try to see what is going on with the dammed thing but could not follow. Typically they would start with a few things I had to spend months googling. The background I want you to assume I have is the following: The ability to take derivatives of functions. The ability to take integrals. I know what a matrix is and can do basic three basic types of matrix multiplication. Throw out all notions of fancy vocabulary and rigor that may come with a good calculus and linear algebra course. Just give me the surface applied tangible stuff I can work with. No fancy notation, from mathematics or physics, just the full bare working thing. If possible one example that has nothing to do with physics, and then one physics example.
