Consider the following matrix

Q := <cos(t), sin(t)>; sin(t), -cos(t)>

If I multiply the first column by the second column (at first glance this would see to be a 2x1 column multiplied by a 2x1 column, which isn't possible), I still get a result. 

(Q[1 .. 2, 1]) . (Q[1 .. 2, 2])

Now this isn't really that big a deal. Apparently, something like Q[1 .. 2, 1] is actually a Vector, so we're actually computing the dot product between two vectors. However, the result is the following

What is the bar over the variable t?
