Complete parts a through c below Find two unit vectors paral

Complete parts (a) through (c) below. Find two unit vectors parallel to v = 6i - 8j. Find b if v= 1/3, b is a unit vector. Find all values of a such that w = ai + a/4j is a unit vector. The parallel unit vector with the same direction is . The parallel unit vector with the opposite direction is . b= . (Type exact answers, using radicals as needed. Use a comma to separate answers as needed.) a = (Type exact answers, using radicals as needed. Use a comma to separate answers as needed.)

Solution

<6/10 , -8/10> , <-6/10,8/10> b = +/- 2sqrt[2]/3 a = +/- 2/sqrt[5]
