Hello I am not professional at physics and new on this forum so don't be angry when I make mistakes(adsbygoogle = window.adsbygoogle || []).push({});

So my question is about wave function so is it right that ψ=Asin(kx)+Bcos(kx) where A and B are constants, k is a some constant k=√2mE/ħ^2 and x is cordinate so when we give A and B value and do little bit math work then we got number. My question is can we describe wave function on some single point ? And can you guys give my steps for solving that beadiful equation on free particle.
