Two colleagues, Fenglin and Leslie, are given two vectors b, v E R to work with, but they are only told projby = ( 3) Fenglin says that they don't have enough information about b and v to do anything useful. However, Leslie 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, Leslie computes the exact value of proj, 12v (not in terms of b or v) to be projb 12v = (b) Next, Fenglin 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 Leslie and Fenglin (remembering your answer should not be in terms of b or v) by computing 223 projb (v + 471 Q P
