Hi everyone.(adsbygoogle = window.adsbygoogle || []).push({});

Long time lurker first time poster.

I am taking a linear algebra class this semester and I am really struggling.

Does anyone have any good resources for learning/understanding function spaces, polynomial interpolation and orthogonal expansion etc..?

Thanks
