Two vectors are perpendicular if there dot product is zero.
if this is wrong place please mvoe i dont know what topic vector belong in
so basically this i sthe qu
find x so the two vectors are perpendiculs
the nfind a cross product
i dont have any source materials/TEXTS before people say read your text book etc which always happen. i am not in school...
Furthermore, here is what I get when I use Google and the search string 'two vectors perpendicular': Google
I'm sure with a little browsing many useful websites would be found ....
The same thing can be done with 'cross product'.
People don't mind helping, but most would prefer that the obvious possibilities for help, some of which admittedly require a little effort, have first been exhausted by the person askng for help.
i didnt say i dont know what makes t wo vector perpemdiculuar
i said i dont know HOW to make them
so what we have here is a power ^T on each side what do u do with this
and fantastic guy the google link dont help. yes i have looked on all those websites and i dont get it thats why im askin help.
The ^T is for transpose:
For all practical purposes the vectors are <1,1,0> and <x,1,-1>. You've been given the tool for solving the question. And if none of the Google links help I'd be greatly surprised.
Where has the question come from and why are you trying to solve it?
but what about this bit
Using the cross product, find a unit vector ^c
so that ^a;^b and ^c are the unit vectors for a right-handed coordinate system.
i have the unit vectors ^a and ^b but what do i need to do next? is it asking me find cross product a and b? or ^a and ^b?
sorry but why is this is PRE university? this is university materiall...
