Question

FIND A^ IF VECTOR A =I^-J^+2K^

Answer 1

A = (x, -y, 2z)

Answer 2

what^ , thats wrong!

Answer 3

A^ I assume means A with a hat over the top.

That means they want a vector of unit length


The length of the vector = sqrt{1^2+1^2+2^2}= sqrt(6)

Answer 4

\[( \frac{1}{\sqrt{6}}, -\frac{1}{\sqrt{6}}, \frac{2}{\sqrt{6}})\]

Answer 5

your quite right elecengineer, the hats (carets) confused me

Answer 6

A^ \[= A / |A| = 1/\sqrt{6} \times (x,-y,2z)\]
