Chapter 9: Q. 57 (page 631)

If $u \times v = 2 i - 3 j + k$ , what is $v \times u$ ?

Short Answer

Expert verified

The vector $v \times u$ is equal to $- 2 i + 3 j - k$ .

Step by step solution

01

Step 1. Given Information

We are given a cross product,

$u \times v = 2 i - 3 j + k$

02

Step 2. Finding the cross product

We know that,

$v \times u = - (u \times v)$

So,

$v \times u = - (2 i - 3 j + k) = - 2 i + 3 j - k$
