[SOLVED] Geometric Algebra: Signs of electromagnetic field tensor components? Here's a question that may look like an E&M question, but is really just a geometric algebra question. In particular, I've got a sign off by 1 somewhere I think and I wonder if somebody can spot it. PF isn't accepting what I wrote (my latex appears to trigger an internal database error), so I've converted it to standalone latex and attached my notes and question as a pdf file. I've also attached what I attempted to post to PF, for reply purposes (so it can be cut and pasted from selectively if desired).
