Figure 8 . Screen output for Listing #3.
Hello from JavaScript vecResultMag = 8.11vecResultAng = 90.49 The End

As you can see, the displacement vector is just a little over eight meters at an angle of about 90.5 degrees. In other words, your ending position wasapproximately 8 meters north of your starting position. Hopefully you were able to arrive at a very similar answer using vector diagram.

Explanation of the code

The code in Listing 3 is very similar to the code in Listing 2 . However, there is more of it because the code is adding four vectors instead of only 2.

As before, Listing 3 begins with the getAngle method that we developed earlier.

Magnitude and angle for each vector

Then Listing 3 defines eight variables containing the magnitudes and angles of the four segments of the walk.

(Note that the names that I used for the variables in this script are somewhat simpler than the names that I used in Listing 2 .)

Horizontal and vertical components

Following that, Listing 3 computes the horizontal and vertical components for each of the four vectors and saves those values in eight different variables.

Sums of components

Then Listing 3 computes and saves the sum of all four horizontal components and computes and saves the sum of all four verticalcomponents.

After that, there is essentially no difference between the script in Listing 3 and the script in Listing 2 .

Other vector operations

In addition to the addition and subtraction of vectors, there are other operations that can be performed using vectors, such as the dot product andthe cross product. However, those operations are beyond the scope of this module.

Run the scripts

I encourage you to run the scripts that I have presented in this lesson to confirm that you get the same results. Copy the code for each script into atext file with an extension of html. Then open that file in your browser. Experiment with the code, making changes, and observing the results of your changes. Makecertain that you can explain why your changes behave as they do.
