I want to check my hand calculations of wedge products of 1-forms such as

yz dx and sin(z) dx

I see that

Wedge

has no built-in meaning. Should I try to define 

Wedge

myself?

I want to use symbols to refer to 1-forms, perhaps a list

phi = {y*z, 0, x}
psi = {z, x, 0}

for yz dx + x dz and z dx+x dy respectively.

Then I want to manipulate them using the operator

Wedge[phi,psi]

    It is safe to define Wegde, if that's what you're asking (unclear what the question is). It has not built-in meaning. – Szabolcs Jul 12 '18 at 17:52
  • Your question may be put on-hold because it's not clear what you need. To avoid or revert the Hold you can [edit] your question to improve it and make it specific, well structured and easy to understand. Please don't be discouraged by that cleaning-up policy. Your questions are and will be most welcomed. Learn about good questions here. – rhermans Jul 12 '18 at 18:31
  • Have you tried the array-based approach of TensorWedge[phi, psi] ? This is a representation of the algebraic part of exterior calculus, but not the differential part. – jose Jul 12 '18 at 21:44
  • Another possibility is to use an external package for full exterior calculus, like http://www.xact.es/xTerior/ , where Wedge does have the meaning you need. See examples in the xTeriorDoc.nb file in that page. – jose Jul 12 '18 at 21:44
