Question
Determine the coordinates of vector
in the basis of
Indice
Solve the system inferred from the equaltiy
Solution
We look for two real numbers
and
such that:
which is equivalent to:
The first equation gives us
and by reporting this in the second one, we have:
which implies
then
The coordinates of vector
in basis
of
are therefore
