ether is a hypothetical medium which scientists of 18th century thought was a medium in which light actually travels from sun 2 earth.
this was before dual nature of light was discoverd by hertz maxwell n other famous experiments.
there is no thing called ether..its just a fictional stuff...there is nio medium b/w sun to earth..only the earths atmospshere at a later stage....
so bfor it was known light travels in vacuum..they called it "ether" medium...
rate if useful.

as vecs b and c are perpendicular..
b.c=0
from thsi we can get the value of c in vector form...(ai+bj+ck)
can be the intiial value for calc. purpose...
get the value of c and sue projection rue

proj=1== x. c div by |c|

from thsi we get vector from of x..
try similarly for da oder vector...
