About the Course

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....

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.

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.

I wish the forums would be a place of exchange of problems among students and professor.

Of the very few errors in the lectures, posting corrections might be valuable as to avoiding loss of hair.

I love the stories of the Japanese math teacher, cos strong, sine mother take the baby out. look at the moon.

Lectures are excellent. Not enough course material to have problems enough to work through to get proficient so I had to find other resources to work through. If They had about 5x as many problems to solve (usually only 5) prior to the exam that would be great.

This course provided absolutely no feedback on any of the quizzes. That isn’t good teaching.
