sorry, but the $^T$ puzzles me a bit. Besides that, good answer, will try it asap

comment Computing cross product using norm and angle
made a mistake in my original question, 1. transforms into $||-7(v\times w)||$

comment Cross product as factor in dot product
thanks so far, I didn't know I could handle cross products like that. I've transformed this into $5v(w \times v)-15w(w \times v)$ although this looks a bit tidier, how can I compute that? Is there a relation between norm and cross product I'm missing here?

I just didn't know the difference, my choice of words wasn't based on any literature
