7. Consider the 2dimensional vectors 13' = (E) and 13 = (11). a) Compute the vector 3:3. Draw all three of the vectors 1?, 18, and 31.3 in the plane. b) Compute the vector if + 313. Draw this vector on the plane, too (adding to your old picture). c) Compute the lengths "fill, \"13\"; and "1? + 323". Can you relate these lengths in any obvious way
