Simplify the following:
(-4, 7) + (4, -4)

Add the corresponding components of the vectors (-4, 7) and (4, -4).
(-4, 7) + (4, -4) = (-4 + 4, 7 - 4):
(-4 + 4, 7 - 4)

Look for the difference of two identical terms.
-4 + 4 = 0:
(0, 7 - 4)

Subtract 4 from 7.
7 - 4 = 3:
Answer:
(0, 3)

Projection of u onto v and v onto u
Given the vector u=<2,6,4> and a vector v such that the vector projection of u onto v is <2,4,4>, and the vector projection of v onto u is <8,24,16>. What is the vector v?
Let v=<a,b,c>
Projection of v on u is given by:
projuv=u.v|u|2u=u.v(2)2+62+42<2,6,4>
<8,24,16u.v(2)2+62+42<2,6,4>
4<2,6,4u.v4+36+16<2,6,4>
<2,6,4u.v224<2,6,4>
On comparing u.v224=1
u.v=224
projvu=u.v|v|2v=224|v|2<a,b,c>
<2,4,4224|v|2<a,b,c>
Dividing both sides by 2 we get:
<1,2,2112|v|2<a,b,c>
