Is there a way to extract the x, y,and z coefficients of a plane?
Given two planes I can find the line of intersection, but see no way to manipulate the a: x+y+z= (whatever) to determine the normal vectors to the planes. I can easily do it manually by manually converting the equations to f(x,y) and g(x,y), but I am obviously missing something. I did try the coefficients command and many, many other things. I'm just trying to break out the x, y, and z components and their coefficients. I can do this in Python or Sage Math, but I'm lazy and Geogebra is generally much faster. I admit I'm probably missing something obvious.
