2 vectors are parallel iff . After computing a+pb we get and with the condition of parallelism we have that , from where we have , for a).
For b), is the same thing, try to solve yourself.
I don't really know if this belongs here, but I couldn't find anwhere to put it. All help appreciated.
Given that vector a = i - 2j and vector b = -3i + j find:
a) p, if 'a + xb' is parallel to -i - 3j
b) q, if 'qa + b' is parallel to 2i + j
Answers: a) 1/2
b) 1
I am looking for some help and working. Advanced thanks.
