Graphical Representation of ChebyshevT Polynomials
Definition
The ChebyshevT polynomials are defined as
\[
\begin{align}
T_n(x) &= \frac{n}{2}\,\sum_{k=0}^{[n/2]} \frac{(-1)^k\,(n-k-1)!}{k!\,(n-2k)!}\,(2x)^{n-2k}\\
&= \frac{1}{2} (2x)^n {}_2F_1 \left(\left. {-n/2, -n/2+\frac{1}{2} \atop -n+1} \; \right| \frac{1}{x^2} \right)
\end{align}
\]
Plot
Note: You can choose a selection on the small graph in order to zoom. Mark the check boxes on the left side for which n you want to plot the graph.
