Find the decomposition a = a<sub>||</sub> + a<sub>?</sub> with respect to b if a = (4, 6, 2), b = (3, 4, 6).
a<sub>||</sub>b = (a<sub>||x</sub>, a<sub>||y</sub>, a<sub>||z</sub>)
a<sub>?</sub>b = (a<sub>?x</sub>, a<sub>?y</sub>, a<sub>?z</sub>)
(Enter the components of vectors using symbolic notation and fractions where needed.)
