Answer 3

orthogonal means perpendicular. Do you know what to do now?

Answer 4

so its 90 degrees

Answer 5

Yes

Answer 6

that angle would be 0?

Answer 7

dot product would be zero

Answer 9

gonal and normal vectors

Answer 10

so It is 0

Answer 11

hint:
2 vectors are orthogonal each other when, their scalar product is zero, namely:
\[\Large u \cdot v = \left\| u \right\|\;\left\| v \right\|\;\cos {\theta _{uv}} = 0\]

Answer 12

well you need to understand why zero

Answer 13

well now I know that is definitely 0

Answer 14

being \[\Large {\theta _{uv}}\]
the angle between such vectors

Answer 15

what you know does not matter, you need to show why it is zero

Answer 16

I found the answer by finding the scalar product at first
