  1. Trigonometry Section 6.4 Vectors and Dot Products

  2. Dot Product • The dot product of vectors u and v is defined as : • u.v = v.u • 0.v = • u.(v+w)= • v.v= • c(u.v)= • Ex 1

  3. More Examples • Ex 2 & 3 • Try the following: • 1. Find the dot product of <5, 12> and <-3,2> • 2. Find 3u.v when u=<2,2> and v=<-3,4> • 3. Use the dot product to find the magnitude of u=<2, -4>

  4. Homework • P. 447 1-14
