Shouldn't the value for Example 1 be (-12)/(sqrt(14)*sqrt(21)) ?

I believe the second radical in the denominator was calculated wrong.

vector A cross vector A = zero? or does it equal the zero vector? Because at the beginning you said that a vector cross a vector gives you another vector. and zero is a scalar.
