Hello, I just have a question about dot products of different coordinate systems.(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering if anyone can explain why unit vector z(rect.) DOT unit vector r(spherical) is equal to cos(theta). As well, I was hoping if anyone could explain z DOT (Theta) = -sin(theta)?
