## The Attempt at a Solution

Well I found:

[tex]

||f|| = \frac{1}{ \sqrt{3}}

[/tex]

[tex]

||g||=\frac{i}{ \sqrt{3}}

[/tex]

[tex]

<f,g> = \frac{1-4i}{17}

[/tex]

Can someone verify the above?

The last question really bothers me. I know that the inproduct must be zero but what does the span explicitly mean? Is it the term below?

[tex]

\alpha \cdot \left( \frac{-1}{2} \right) ^n + \beta \left( \frac{i}{2} \right) ^n

[/tex]

But if that's the case how can I find h?
