Vectors & Scalars in Math - Chapter Summary

In this chapter, our instructors present you with vectors in physics and demonstrate how they can be manipulated in math. These interesting lessons explain the difference between scalars and vectors and show you how to use geometry to add vectors. You'll review basic calculations involving scalar multiplication and understand how to find the cross product of two vectors. Other topics include the triple scalar product, which occurs when you multiply three vectors together. This informative chapter prepares you to do the following:

  • Graph vectors with regard to direction and magnitude
  • Add, subtract, multiply and divide vectors
  • Find the dot product of vectors using algebra and geometry
  • Calculate the direction of a vector when given the x and y components
