Question: Let

Show that fⁿ(0)=0 for n=0,1,2.... and hence that the Maclaurin series for f(x) is 0+0+0+.... , which converges for all x but is equal to f(x) only when x=0 . This is an example of a function possessing derivatives of all orders (at x₀=0 ), whose Taylor series converges, but the Taylor series (about x₀ =0) does not converge to the original function! Consequently, this function is not analytic at x=0.

In problems 1-6, determine the convergence set of the given power series. $\sum_{n = 0}^{\infty} \frac{2^{- n}}{n + 1} {(x - 1)}^{n}$

In Problems 1-10, use a substitution y=x^r to find the general solution to the given equation for x>0.

x²y"+2xy'-3y=0

In Problems 1-10, use a substitution y=x^r to find the general solution to the given equation for x>0.

x³y"'+4x²y"+10xy'-10y=0

(a) Use (20) to show that the general solution of the differential equation $xy'' + \lambda y = 0$ on the interval $(0,\infty )$ is$y = {c_1}\sqrt x {J_1}\left( {2\sqrt {\lambda x} } \right) + {c_2}\sqrt x {Y_1}\left( {2\sqrt {\lambda x} } \right)$.

(b) Verify by direct substitution that $y = \sqrt x {J_1}\left( {2\sqrt {\lambda x} } \right)$is a particular solution of the DE in the case $\lambda = 1$.
