Question 1201409: From vector addition/subtraction lesson:
Each of the following vector expressions can be simplified and written as a single
vector. Write the single vector corresponding to each expression and illustrate your answer with a sketch.
a.
--> --> -->
PQ - RQ + RS
b.
--> --> --> -->
PS + RQ - RS - PQ
You can put this solution on YOUR website! .
a.
--> --> -->
PQ - RQ + RS
b.
--> --> --> -->
PS + RQ - RS - PQ
~~~~~~~~~~~~~~~~~~~~~~~~~~~
(a) PQ - RQ + RS = PQ + QR + RS = PS , according to the base rule of addition vectors.
(b) PS + RQ - RS - PQ = PS + RQ + SR + QP = (re-group addends) = PS + SR + RQ + QP = 0 (zero vector, since we have a closed contour).
If I understand it correctly, it is in the style of April-1 Math jokes . . .
