What is the unit vector that is normal to the plane containing <2i+7j-2k> and <8i-2j+3k>?
The unit vector is
Using the determinant (cross product), one can calculate the vector perpendicular to two vectors.
Consequently,
Verification using the two dot method
Thus,
The vector of units is

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
