Question

Choose any two vectors x and y. Show, algebraically and with the use of a diagram, that x + (y-x/2) = (x+y/2) HELP PLEASE!

Answer 1

@Chlorophyll, @Hero, @ilikephysics2, @TuringTest can any of you answer this question? :$ :$

Answer 2

\[x + \frac{ y-x }{ 2 } = \frac{ x+2 }{ 2 }\]

Answer 3

anyone? :$

Answer 4

I'd have to brush up on vectors bro

Answer 5

oh shoot :(

Answer 6

if its confusing because they are vectors, just think of them as normal variables. \[x+\left(\frac{y-x}{2}\right)=x+\frac{y}{2}-\frac{x}{2}\]try to get it from there.

Answer 7

i don't know if I have the right approach but is it like this way:

\[x + \left(\begin{matrix}y \\ 2\end{matrix}\right) - \left(\begin{matrix}x \\ 2\end{matrix}\right)\]
\[2x + y - x + x + y\]

Answer 8

help?
