Hello, and welcome to oneCalculus!
My name is Alexander Coward and I set up oneCalculus to support students at UC Berkeley in freshman mathematics classes. Right now I'm focusing on creating materials and support for students in Math 16A and Math 1A. Over time I'll be adding other classes. If you're stuck on any topic in Math 1A or Math 16A, you're welcome to come to my office hours at the Free Speech Movement Cafe, on Fridays from 2pm to 4pm for the whole of the Fall Semester.
My reason for creating this site is that I taught mathematics at UC Berkeley between 2013 and 2016. During that time I saw a lot of students struggling with their freshman math classes because professors thought that the purpose of those classes was to "weed" students and bring in money to the mathematics department, rather than provide a great education.
