LEARNING GOALS Scalar Multiplication Unit Vectors Collinear Vectors Linear Combinations Review of Sine and Cosine Law Physics Applications of Vectors
SCALAR MULTIPLICATION
UNIT VECTORS
UNIT VECTORS EXAMPLE
COLLINEAR VECTORSVectors are collinear if they lie on a straight line when arranged tail to tail. The vectors are also scalar multiplies of each other, which means that they are parallel.
All are examples of collinear vectors!!

REQUIRED BEFORE NEXT CLASS Review your notes for the whole chapter,
there may be a pop quiz tomorrow Read Section 6.3 and make notes Section 6.3 # 4, 11, 19, 21 Add me on Facebook, Peter Bishop, but be sure
to send a message along with it indicating which class you are in, and what section.
Join the Facebook group for Calculus and Vectors Write to me your e-mail, so I can send you an
invitation into dropbox, which will be used throughout the course.
