\[\left [y \left (x \right ) = \textit {\_C1} x +\textit {\_C2} \sqrt {x -1}\, \sqrt {x +1}\right ]\] Mathematica raw input
DSolve[y[x] - x*y'[x] + (1 - x^2)*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> C[1]*Cosh[(Sqrt[1 - x^2]*ArcSin[x])/Sqrt[-1 + x^2]] + I*C[2]*Sinh[(Sqr
t[1 - x^2]*ArcSin[x])/Sqrt[-1 + x^2]]}}
Maple raw input
dsolve((-x^2+1)*diff(diff(y(x),x),x)-x*diff(y(x),x)+y(x) = 0, y(x))
Maple raw output
[y(x) = _C1*x+_C2*(x-1)^(1/2)*(x+1)^(1/2)]
