O, A, B are points in R2. 0 = (0, 0). a) Decide a point A, such that 3
O, A, B are points in R2. O = (0, 0). a) Decide a point A, such that 3 < IOAI < 4. Decide a point B, such that 5 < IOBI < 6, and 500 < LAOB < 800. Hint: find IABI and use the cosine law. A sketch or Geogebra screenshot helps. b) Come up with a point C, such that OA + 0B + oc = o. c) D = (10, -8), and OD = t.0A + s.OB. Solve fort and s.
