Would it just be making alpha of
I am going to transform into via the specified rotations. Since can be transformed into , does it suffice to show the one transformation? Or if I want to show that can be transformed into , must I demonstrate it as well?
Since both these equations can be transformed into each other, should they have the same general solution? For , I obtained , and if , then . However, for , I obtained . Thanks.
