Homework Statement


Find two vectors v and w that are perpendicular to (1, 0, 1) and to each other.


Homework Equations


I know that to be perpendicular, the dot product must be 0. So (1, 0, 1)*(x, y, z)=x+z=0 and x=z=0, y=1, therefore, v=[0, 1, 0]. w=[-1, 0, 1].


The Attempt at a Solution


Are my answers right for v and w? Can someone right the answer for me? I just want to see how the answer looks like.

It's easy enough to check your answers to see if they're correct.

Is v ##\cdot## <1, 0, 1> = 0?
Is w ##\cdot## <1, 0, 1> = 0?
Is v ##\cdot## w = 0?

Thank you guys.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
