# Cross product

I have a question about solving a problem involving a cross product. I understand how to find $$\vec{a}$$ X $$\vec{b}$$ = $$\vec{c}$$, but if $$\vec{a}$$ and $$\vec{c}$$ are given how do I find $$\vec{b}$$? Is there something I can do analogous to c/a =b? I've been reviewing my old calc III and linear algebra notes, but I havn't been able to figure it out. Any help would be most appreciated.

Thanks
