Example Question #1 : Vector Calculations

Find the cross product of the following two vectors:

Possible Answers:

Correct answer:

Explanation:

We obtain the cross product of the two vectors by setting up the following matrix:

Where our first row represents the unit vectors, the second row represents vector a, and the third row represents vector b. The first component of our cross product is obtained by taking the determinant of the matrix left by crossing out the row and column in which  is located. Accordingly, our second and third components are found by taking the determinant of the matrix left by crossing out the rows and columns in which    and    are located, respectively. This process gives us the following simple equation for expressing the cross product of two vectors, into which we can plug in the components of our vectors to find the cross product:
