Problem 1 :
Determine whether the three vectors
are coplanar.
Solution :
Problem 2 :
Let
If c1 = 1 and c2 = 2, find c3 such that
are coplanar.
Solution :
After applying the values of c1 and c2, we get
Problem 3 :
If
show that
depends on neither x nor y.
Solution :
Problem 4 :
If the vectors
are coplanar, prove that c is the geometric mean of a and b
Solution :
Since the vectors are coplanar,
Problem 5 :
Let
the three non zero vectors such that c vector is a unit perpendicular to both a vector and c vector. If the angle between a vector and b vector is π/6, show that
Solution :
c vector is perpendicular to both a vector and b vector. So, c vector is parallel to (a vector x b vector)
Squaring on both sides,
