The scalar product of two vectors a and b, denoted a ยท b, is defined as | a | | b | cos ฮธ.

The scalar product of two vectors a = xi + yj + zk and b = pi + qj + wk, denoted a ยท b, is defined as xp + yq + zw.

If two vectors a and b intersect at an angle of ฮธ, then cosฮธ = a ยท b/| a | | b | where a ยท b is the scalar product of vectors a and b.

If two vectors a and b intersect at an angle of ฮธ, then cosฮธ = a ยท b/|a| |b| where a ยท b is the scalar product of vectors a and b.
