Does Three-dimensional space has any use in real analysis particularly in measure the
I am self teaching myself and due to no money plus time I can't join University, but I want to study maths on my own, therefore please guide me.
I have adapt a route calc1->calc2->calc3->differential equation->introductory linear algebra->introductory abstract algebra-> real analysis->measure theory->probability theory, so that I can study topics as stochastic process, brownian motiion etc. is this route sounds OK?
currently I am studying calc2 and I was wondering if I really need to study three dimensional spaces and/or vectors or not, does it not use only in computer graphics, physics etc sort of stuff?
Thanks in advance
