# Help to understand the basis for a dual space
I've been introduced to the concept of dual space in linear algebra. I can understand perfectly that the dual space of the space $V$ is a space $V^*$ made of all possible linear maps from $V$ to $\mathbb{R}$. So, for example, let $V$ be $\mathbb{R^3}$, then we have, as e... | HuggingFaceTB/finemath | |
