Objectives for Calculus III

Geometry and Vectors

  • Use the parallelogram law to add geometric vectors. Resolve geometric vectors into components parallel to coordinate axes.
  • Perform the operations of vector addition and scalar multiplication, and interpret them geometrically.
  • Use the dot product to calculate magnitude of a vector, angle between vectors, and projection of one vector on another.
  • Find and use direction angles and direction cosines of a vector.
  • Use parametric equations for plane curves and space curves.
  • Use and convert between parametric and symmetric equations for a straight line.
  • Find a tangent line at a point on a parametric curve; compute the length of a parametric curve; compute the area of the surface generated by revolving a plane curve about an axis.
  • Compute velocity, unit tangent and acceleration vectors along a parametric curve; resolve acceleration into tangential and normal components and compute curvature.
  • Use and interpret geometrically the standard and symmetric equations for a plane.
  • Use the cross product; interpret the cross product geometrically and as the area of a parallelogram; interpret the vector triple product as the volume of a parallelopiped.
  • Recognize cylinders and quadric surfaces from their Cartesian equations.
  • Use cylindrical and spherical coordinates, and convert among these two and rectangular coordinates.

The Derivative in n-Space

  • Represent a function of two variables as the graph of a surface; sketch level curves.
