Taylor Expansion Question about this Series

Click For Summary
SUMMARY

The discussion centers on the Taylor series expansion represented by the equation f(x+α)=∑(n=0 to ∞) (α^n/n!) (d^n f/dx^n). This series is specifically expanded around the point x, as indicated by the power series in α. To enhance clarity, it is recommended that the derivatives be explicitly evaluated at x, which would provide a more straightforward understanding of the series.

PREREQUISITES
  • Understanding of Taylor series and their applications
  • Familiarity with calculus, specifically differentiation

Can you please explain this series
f(x+\alpha)=\sum^{\infty}_{n=0}\frac{\alpha^n}{n!}\frac{d^nf}{dx^n}
I am confused. Around which point is this Taylor series?

THis is an expansion about x. You can tell that because the series is a power series in \alpha.
 
It would help if the derivatives were explicitly evaluated at ##x##. Then it would be clearer.
