CAS Maple gives this as type [_linear]

\[ \boxed {y^{\prime } x -827 y=-\cos \left (x^{2}\right )} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 22

dsolve(x*diff(y(x),x)+cos(x^2)=827*y(x),y(x), singsol=all)
 

\[ y \left (x \right ) = \left (-\left (\int \frac {\cos \left (x^{2}\right )}{x^{828}}d x \right )+c_{1} \right ) x^{827} \]

Solution by Mathematica
