Question

Determine the projection of vector a onto vector b. Next, express vector a as vectors, a₁ and a₂, where a₁ is parallel to vector b and a₂ is perpendicular to vector b.
a = 11i -j, b = 3i +9j

Accepted Answer

a_{1} = proj_{b}(a) = (4/5)i + (12/5)j, a_{2} = (51/5)i -(17/5)j

Answer

a_{1} = proj_{b}(a) = (8/3)i + 8j, a_{2} = (25/3)i - 10j

Answer

a_{1} = proj_{b}(a) = (8/3)i - 8j, a_{2} = (25/3)i + 10j

Answer

a_{1} = proj_{b}(a) = (4/5)i - (12/5)j, a_{2} = (51/5)i +(17/5)j
