Lesson 9.7
Today in math

GOAL


: the magnitude of a vector AB is the distance from the initial point A to the terminal point B and is written AB




:the direction of a vector is determined by the angle it makes with a horizontal line.




: Two vectors are equal if they have he same magnitude and direction.




:Two vectors are parallel if they have the same of opposite directions.




Sum Of Two Vectors


The sum of two vectors of u = { a1, b1} and v={a2, b2} is u+v= {a1+a2,b1+b2}.
