If `vecp, vecq , vecr` denote vectors `vecbxxvecc, vecc xx vecc xx veca, vecaxx vecb`. Respectively, show that `veca` is parallel to `vecq xx vecr , vecb` is parallel to `vecrxx vecp , vecc` is parallel to `vecp xx vecq`.\

Explanation

To show that the vectors \( \vec{a} \), \( \vec{b} \), and \( \vec{c} \) are parallel to the respective cross products as stated in the question, we can follow these steps:

### Step 1: Define the vectors
Let:
- \( \vec{p} = \vec{b} \times \vec{c} \)
- \( \vec{q} = \vec{c} \times \vec{a} \)
- \( \vec{r} = \vec{a} \times \vec{b} \)
