This year in pre calculus, we covered coordinate geometry, linear algebra, and matrices. We completed several unit projects to learn about these topics, such as the orchard hideout project for circles, and the malls and meadows project with matrices. My favorite unit was the malls and meadows because I enjoyed solving the systems of equations using matrices, and using desmos matrix calculator to get results. I was challenged by the orchard hideout unit, but I eventually understood it.
