课程概述

This course helps to build the foundational material to use mathematics as a tool to model, understand, and interpret the world around us. This is done through studying functions, their properties, and applications to data analysis. Concepts of precalculus provide the set of tools for the beginning student to begin their scientific career, preparing them for future science and calculus courses. This course is designed for all students, not just those interested in further mathematics courses. Students interested in the natural sciences, computer sciences, psychology, sociology, or similar will genuinely benefit from this introductory course, applying the skills learned to their discipline to analyze and interpret their subject material. Students will be presented with not only new ideas, but also new applications of an old subject. Real-life data, exercise sets, and regular assessments help to motivate and reinforce the content in this course, leading to learning and mastery....

The course content is great, but despite dozens of moderators, they never answer any questions in the discussion, so you better be able to pass completely on your own.

This was a very good course. The lecture videos were long enough to explain everything and not bore you to death. I rated this course 4/5 stars because in all of the quizzes and module exams, there were problems that the professor did not cover in the lectures. The provided sample problems were incredibly detailed, however, in many cases, they did not help in solving the quiz problems. You have to look outside the course for help since the discussion forums are dead at this point (Feb 2024). I am used to doing this so it did not affect me that much, but for those who are new to the subject or need a refresher, this will definitely discourage them. The professor teaches at Johns Hopkins University and the textbook they use in their in-person course is "PreCalculus by Faires and DeFranza".

The course is good. It is a continuation of the algebra courses that were awesome. The lectures are clearer than any math teacher I ever had in school. A few of the exercises are a bit frustrating in this course, though. In the algebra courses, we were given feedback on incorrect answers. In this course, all of that feedback is missing. When you get an answer wrong on a quiz, you don't see a solution worked out to help you figure out why you got it wrong. A lot of the questions involve entering the answer as a rounded decimal. When I get those wrong on occasion, I would love to know if I got the answer incorrect because I screwed up the math or because of an issue with a silly rounding mistake.

If there were adequate feedback, I'd give this course 5 stars without hesitation.

I thought it was a good course. It could be quite challenging at times, though, and I would recommend anyone taking it have either a solid grounding in Algebra or have taken the perequisite Algebra course from the same professor.
