USE EXACT NUMBERS... NO DECIMALS, PLEASE EXPLAIN*
Complete parts (a) through (c) below. Find two unit vectors parallel to v = 3i + 4j. Find b if v= (1/7,b) is a unit vector. Find all values of a such that w = ai + a/2j is a unit vector. The parallel unit vector with the same direction is . The parallel unit vector with the opposite direction is . (Type exact answers, using radicals as needed. Use a comma to separate answers as needed.) (Type exact answers, using radicals as needed. Use a comma to separate answers as needed.) Show transcribed image text
