What are the properties of vector addition -
CORRECT ANSWER-Commutative and
associative
Commutative in terms of vector addition -
CORRECT ANSWER-a + b = b + a
Associative in terms of vector addition -
CORRECT ANSWER-(a +b) +c = a + (b + c)
Order in which vectors are added does not matter
What are the two distributive laws that scalar
multiplication and vector addition obey? -
CORRECT ANSWER-lambda*(a+b) = lambda*a
+lambda*b
(lambda +mu)*a=lambda*a + mu*a
Equation of a line with points A and B being on
the line - CORRECT ANSWER-r = a + lambda*(b-
a)
r = a + lambda * (unit vector - t hat)
