This course teaches you the fundamentals of integration and sequences & series. If you didn't learn integration in high school calculus then this course is essential for success in future math classes.

Integration (Riemann sums, Fundamental Theorem of Calculus, techniques; arc length, area, volume, and surface area of curves using single integration; average value, improper integrals), sequences + series (convergence / divergence tests, geometric series, telescoping series, error estimates).

Very nice professor.

Use online calculators to check your work. Tutorials introduce more challenging questions that help you solidify your understanding.
