Using the quotient test (or radio test), ##\frac{a_{n+1}}{a_{n}} \rightarrow x^2*\sin(\frac{\pi \cdot x}{2}), n \rightarrow \infty##.
However from here I'm stuck, as there seems to be no way for me to determine a radius of convergence. Furthermore even if I could find the radius, the book we are using talks about Weierstrass Mtest, and several other methods of figuring out IF a sum is uniformly convergent, but none of these methods seem to yield and actual interval. Please assist.
