centerline{bf Projection}

Let us give names to the vectors, and write the vectors vertically for convenience at the last stage:
$$
vec a = l(matrix{0cr 1cr 2}r), ~~~~
vec b = l(matrix{1cr 1cr 0}r), ~~~~
vec c = l(matrix{1cr 1cr 1}r),
eqno(1)
$$
and let us ask temporarily for it more rm than is actually required: decompose an arbitrary ...
