how to solve this? As the rows are dependent I only get 2x+y-3z=0. What am I supposed to do from here? I have no other idea then guessing solutions. I know the solution is this but I don't get how I should calculate it from the point 2x+y-3z

Two of the variables are free. For instance set b = r and c = s, and solve for a in terms of those parameters.
That’s the general solution. Then what’s left is to write it in the form of vectors and the parameters r and s.

You actually get an entire plane of solutions. If you let y=lambda, z=mu then you should be able to write (x,y,z) in terms of lambda and mu the manipulate this so that it can easily be seen it’s a plane.

Can anyone tell me do I use minus or plus here? I know what to do to get the equation if it's "fine angle" or "Obtuse angle" But don't know what to do when it's an Isosceles of a right angle.

Why can e, the number you get by doing 100% compound interest over infinite time periods, also be calculated by summing (1/x!) to infinity? What's the correlation/what does compound interest have to do with inverses of factorials?
