Vector question urgent!!!

[smiley_1332]

How do you find a unit vector that is perpendicular to two other vectors given? Please answer ASAP!!!

vector cross product, the resulting vector will be perpendicular to the 2 given vectors, but for a unit vector you just divide the new vector by its magnitude

Multiply the unit vector with the 2 other vectors giving you 2 equations. Then you third vector is x^2+y^2=z^2=1 since magnitude of a unit vector is 1. These type of questions are very common.

I believe x^2+y^2+z^2=1 describes a plane, which is not a part of the course. Heck even the cross product is not a part of the course

Well it's just meant to be seen as an equation, not a sphere... so yeah this question is within spesh.
