Answer:
Step-by-step explanation:
given are two vectors
a) A+B = sum of twovectors = simply adding corrsponding compnents
=
Magnitude of the above vector =
Direction is making an angle of arc tan (-3) with x axis
b) A-B = Difference
=
Magnitude of difference vector =
Direction is making an angle of arctan (1/2) with positive x axis.
(angle = arctan (jcomponent/icomponent)
Both equations start with y =
Set both equations equal to each other and solve for x first:
1/3x-4 = -7/3x +4
Add 7/3x to both sides:
8/3x - 4 = 4
Add 4 to each side:
8/3x = 8
Divide both sides by 8/3
x = 3
Now you have the value of x, replace x in the equation to solve for y:
y = 1/3(3) -4 = 1-4 = -3
y = -7/3(3) +4 = -7+4 = -3
y = -3
X = 3 and y = -3
