Two colleagues, Sagar and Harvey, are given two vectors b, v E IR- to work with, but they are only told projb V = Sagar says that they don't have enough information about b and v to do anything useful. However, Harvey says they only need to calculate other related projections for their work. Syntax advice: Use correct Maple syntax to input your column vectors with numerical entries below. For example, the vector would be written as (a) Firstly, Harvey computes the exact value of proj, 12v (not in terms of b or v) to be projb 12v = (b) Next, Sagar starts to figure out what's going on, and computes (not in terms of b or v) proj12b V = (c) Finally, using the above or otherwise, help Harvey and Sagar (remembering your answer should not be in terms of b or v) by computing -612 projb v + 564
