a)
a.b = |a||b| cos ( theta)
theta = angle between a vector and b vector .
a.b = 3.9 * 3.1 cos ( 90 degrees )
= 0
b)
a.c = |a| |c| cos ( theta )
theta = angle between vector a and c .
theta = tan^-1 (b/a)
= 38.48 degrees
a.c = 3.9*5.0 cos(38.48 degrees)
= 15.26
c)
theta = 51.52
b.c = |b| |c| cos ( 51.52 )
= 9.6
