# How do I find the cross product of #<-13, 4># and #<-56, 0>#?

##### 1 Answer

You have two options to evaluate the cross product:

1) the cross product of two vectors

2) evaluate the determinant:

In your case I would use the second option and use the first to check the result. So:

So basically, the result is a vector in the positive

Using the first approach you get the same result considering:

Try to evaluate the modulus (using
