I'm a beginner at differential geometry.(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem about dual space. I understand why we use [tex]\left\{\frac{\partial}{\partial x^{\mu}}\right\} [/tex] as the bases in vector space, but I have no idea why

we use [tex] \left\{ dx^{\mu} \right\} [/tex] as the bases of dual space. What is the reason

of using it?
