Cross product

In this blog, i'm going to talk about the cross product.

 

1. The cross product : it actually has a lot of differences compared to the dot product. First, The dot proudct is defined in any dimension. So this is defined for any two vectors that are in Rn. But the cross product is only defined in R3. And the dot product results in a scalar, which means you just get a number. But in the cross product, we're going to get another vector. And the vector we're going to get is actually going to be a vector that's orthogonal to the two vectros that we're taking the cross product of.

 

2. How to do the cross product ?
