VECTOR
Imagine a three dimensional reference frame. With respect to origin there are two points P(3,-4,5) and Q (2,-1, 1). The position vector of P and Q are indicated by ๐โ and ๐โ respectively.
a) Determine the
position vector of P. Find a unit vector parallel to ๐๐โโโโโ .
b) If ๐โ and ๐โ indicate two adjacent sides of a triangle, what is the area of the triangle?
c) Suppose in your reference frame another vector ๐ โ = ๐ฬ + 2 ๐ฬ โ 3 ๐ฬ
. If ๐โ , ๐โ and ๐ โ indicate three sides of a cubic
