Linda asks…I am bad at Calculus and Vectors explanations, can someone help me out?Given two points, A(5,3) and B(7,2) describe how to find the coordinatesand the magnitudev of the Cartesian vector AB?admin answers:The vector of the point A(5,3) is 5i+3j . The vector of the point B(7,2) is 7i+2j.
Vector AB = vector B - vector A.
Ie --> (7i+2j) - (5i+3j)
= 2i - j
magnitude is ? which is?5.
Hope that answers the question :)Nancy asks…Where can I find some simple tips/explanations
