Complex Puzzle


This activity follows on from Into the Wilderness.


 

 

In this diagram, there are several points and the unit circle (the circle with centre at the origin and radius 1).


The points $a$ to $h$ are the sum or product of combinations of $u$, $v$ and $w$.
Can you work out which of the expression below describes each point? 

$u + v$
$u + w$
$v + w$
$u + v + w$
$uv$
$uw$
$vw$
$uvw$
