According to my notes, the Taylor series of $\sin(x)$ converges uniformly on $[-\pi,\pi]$.
I know that the remainder term needs to converge uniformly to $0$ for this to be the case.
But I really don't know how to begin showing that this series converges uniformly. I think it's the domain that really stumps me. I think I should start showing that the remainder term converges to $0$. So we have:
$$R_n= \frac{(x-x_0)^{N+1}}{N!}\int_0^1 (1-t)^Nf^{(N+1)}(x_0+t(x-x_0))dt$$
Where $R_n$ denotes the remainder term.
What should I do?
Thanks in advance.
