Instructors may want to consider the following adjustments to the schedule as stated above:

- Instructors should consider covering section 4.8 on antiderivatives after introducing Riemann sums and right before the Fundamental Theorem of Calculus in section 5.4 and also consider waiting to introduce indefinite integral notation until section 5.5.
- Instructors may find that they can discuss a wider variety of applications of integrals if the integration techniques in chapter 8 are covered before the applications in chapter 6. (The exercises in the textbook are structured under the assumption that students have only seen substitution when they encounter the applications in chapter 6, with further applications that use advanced techniques included in chapter 8.)
- Time permitting, instructors may consider adding an additional half-lecture on numerical integration error analysis in section 8.7.
- Time permitting, instructors may consider covering section 11.5 (areas and lengths in polar coordinates) immediately after section 11.4. This is a particularly appropriate way to conclude the class as it re-introduces the idea of a Riemann sum from the beginning of the class in the context of polar functions.

**Learning Goals:**

Students will learn the fundamentals of integral calculus. The course begins with the integral of a continuous function defined as the limit of its Riemann sum before the Fundamental Theorems of Calculus presents integrals as anti-derivatives. Integrals are applied to many problems in physics, including area, volume, arc length and surface area. Various techniques of integration are studied and include u-substitution, integration by parts, integration by partial fractions, and trigonometric substitution. After applying integrals to separable differential equations, the course concludes with the calculus of parametric equations.

This course is a pre-requisite for multi-variable and vector calculus. Mastery of this course would be manifested in improved reading, writing, thinking, and problem solving skills. Students should have an increased ability to understand, visualize, categorize, model, and solve complicated calculus problems in both two- and three-dimensional space.
