The summary is:
The lecturer introduces the course on introductory calculus and gives some practical information, such as the lecture notes, the reading list, and the schedule. He then explains the topics that will be covered in the course, such as differential equations, line and double integrals, and calculus of functions in two variables. He also mentions how the course is related to other courses in mathematics and physical sciences. He then gives some examples of differential equations from mechanics, engineering, and radioactive decay. He reviews some techniques of integration, such as integration by parts, substitution, and reduction formula. He solves some integrals using these techniques and shows how to find the general solution of a separable differential equation. He warns about the possible pitfalls of dividing by a function in y and how to include the case when it is zero. He concludes the lecture and invites questions from the students.
Here are the key facts extracted from the text:
