Question 1056874
.
One question per post, please.


It is the RULE of this forum.



And, please, be more accurate in your writing next time.



For example, let assume (for a minute) that I want to ask your question #1:


1)Let q1 = 1+ i + j + k and q2 = 1. Find
(i)q^2 1, (ii)q^2 2, (iii) q1q2, (iv)q2q1


What are i, j, k here? Quaternion units?
Why do not say it at very beginning?
How can I recognise them otherwise?


What is (i)q^2 1 ??


What is (ii)q^2 2 ???
