I have three given points, A, B and C, each of them is a corner of a pyramid. Another corner is located in origo.
The task is to set up a determinant to describe the pyramids volume.
Unfortunately, my book and Wikipedia won´t agree on how to do this, that´s why I´m asking you guys.
PS. The follow up question is if the volume would be any different if the position vectors (a, b and c) and origo all where located in the same plane?
Any help would be very appreciated!
