This unit covers advanced integration techniques, methods for calculating the length of a curved line or the area of a curved surface, and "polar coordinates" which are an alternative to the Cartesian coordinates most often used to describe positions in the plane.
Part A: Trigonometric Powers, Trigonometric Substitution and Completing the Square
Part B: Partial Fractions, Integration by Parts, Arc Length, and Surface Area
Part C: Parametric Equations and Polar Coordinates
