Question

Find the magnitude and direction of vector XY for X(1, -4) and Y(6, 3). Show all work.

Answer 1

XY= (6-1,3-(-4))= (5,7)
tan @=7/5 so @=54.46 degrees with positive x axis
and magnitude = sqrt(25+49) = sqrt(74)

Answer 2

Are you asking X (dot) Y (dot product) or X + Y? X (dot) Y = (6, -12)--> magazine = sqrt(36 + a hundred and forty four), course = 360 - arctan(12/6) X + Y = (7, -a million)--> magazine = sqrt(50), course = 360 - arctan(a million/7) desire this helps!
