Answer 1

first off Diya, can you write any vector at 30deg to x the xy-plane ?
we can change it into a unit one later

Answer 2

first draw such vector to get the ratios

Answer 3

- so because x with y write an angle of 90 degree you need to part this ange in 3 equales parts and after you will get this line sure

Answer 4

Hm i dont get it

Answer 5

do you know how to write vectors in general, or is this all new to you?

Answer 6

yeah i know

Answer 7

ok, hten write me any vector at an angle of 30deg
