\begin{align*} 16 x^{2} y^{\prime \prime }+16 x y^{\prime }+\left (16 x^{2}-1\right ) y&=0 \end{align*}

✓ Solution by Maple

Time used: 0.004 (sec). Leaf size: 15

dsolve(16*x^2*diff(y(x),x$2)+16*x*diff(y(x),x)+(16*x^2-1)*y(x)=0,y(x), singsol=all)
 

\[ y = c_{1} \operatorname {BesselJ}\left (\frac {1}{4}, x\right )+c_{2} \operatorname {BesselY}\left (\frac {1}{4}, x\right ) \]

✓ Solution by Mathematica

Time used: 0.017 (sec). Leaf size: 22

DSolve[16*x^2*D[y[x],{x,2}]+16*x*D[y[x],x]+(16*x^2-1)*y[x]==0,y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to c_1 \operatorname {BesselJ}\left (\frac {1}{4},x\right )+c_2 \operatorname {BesselY}\left (\frac {1}{4},x\right ) \]
