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 is challenging. I learned a lot about trigonometric functions and their behavior. I can now understand periodic ODEs better now...

This course just like the preceding one is brilliant. After a very very very long time I can finally grasp the concepts undelrying the mathematics I studied at the high school.

Excellent course. Trigonometric concepts that, in previous courses, had been intimidating, confusing and tedious became dramatically less so.

As usual, I enjoyed this course taught by Dr. Cutrone and learned a lot. Occasionally, though, I felt there was a gap between what was taught and what was tested. Perhaps that was the intent so that learners would push themselves beyond the presented material.

Instructor quite a good presenter of this material, generally not stiff and pretty colloqial in his language. Made the material interesting and not overy theoretical. I think a couple of the test/quiz questions were not fairly graded ( thought my answer was identical to the shown correct answer); but it was not often enough to be material to my end result. I would certianly recommend this course for the material, and be more likely to take a course with this instructor.

Wonderful course which explains the concepts rather than cramming equations, highly recommended for newbies in mathematics as well as people who have some math knowledge.

Mr Cutrone breaks things down cleanly and his online lectures are a treat. These are followed with notes that go into more detail, followed by practice questions, and then tests which get more grueling as the course progresses. But no matter if you fail - try again, and you might even get some additional questions in the test that you hadn't seen before. This shows Cutrone's dedication to constructing the course.

I enjoyed the course through and through. Joseph is a great instructor. I had not the slightest trouble videos are simple to comprehend and very to the point. I had no question but one which was responded to shortly after I brought it up in the discussion forums. I shall like to recommend this course to a friend.

The course is amazing. It helped me to understand the logic of periodic functions instead only memorize those functions. I think It would be great to provide additional material or books recommendations.

Excellent course in Precalculus, AP Calculus of Periodic Functions and Elementary Trigonometry. It requires a good mathematical background, and it does not include introductory concepts.
