i know that there could be the use of integrals in orthogonal things
Erm... perhaps you should elaborate...
the use of integrals in orthogonality
question about that
maybe polinomials vectors
i need a question that asks about such stuff

yes like this one
do you have an example?
Do a search on "inner product space"
