RE: Win SBD in this Math Contest #1 - Simplify:
Thanks for your question, but I dun really understand it
What is your (x,y) plane referring to? The Argand plane?
If so, since on the Argand plane x-axis refers to the real part, y-axis refers to the imaginary part, ux means 1+0i. And i itself can be written as 0+1i. Multiplying these two, we have i again, so the answer is simply i.
Thanks for your answer.
The (x,y) is the real plane with a real x axis and a real y axis.
Just in case you're interested, I posted a hint today:
