# Test yourself: Functional modeling and linearization

## How well have I met the learning outcomes?

The following are quizzes and solutions I’ve used when teaching these topics in the classroom environment:

Feel free to use them to test yourself too.

I’d recommend doing this only after having completed the following lessons and the associated self-assessment questions.

And I’d suggest sitting down and simulating the same test environment: open book; open device; 35-40 minutes. Use it to figure out whether the lectures notes you’ve been creating for yourself are sufficiently strong and accessible to help you through, and whether your work on the self-assessment questions has given you a solid understanding.

You can do whatever works best for you, of course, but I’d also recommend only looking at the solutions after you’ve completed the assessment.

#### Guidance on using Excel to be efficient with your time in a quiz like this

This video helps you get quicker but it also helps you carry all of your numbers through with enough significant digits, something that will be helpful in the future and even later in this course once we get to matrix operations for the topic in which you’ll be introduced to geospatial estimation.

Note: The quiz question I show in this video was a version that had the 3rd and 4th points labeled differently. The solution file and the Excel file in the video match the quiz question as posed in the version linked above. (Incidentally, if you were to swap points 3 and 4 the only difference anyway would be swapping the 3rd and 4th rows of the A matrix.)

Note: I used approximate coordinates of the drone of zero, i.e. X0 = 0.00 m and Y0 = 0.00 m (because we’re told it launches from the origin) but you could also justify using very small values, such as X0 = 0.01 m and Y0 = 0.01 m – as long as they aren’t too big for reasons we’ll see later in the course. Doing this would just make your calculations a bit harder (fewer convenient repeats). In Excel that’d be okay though, since it’s pretty fast there anyway.
