CAS Maple gives this as type [_linear]
\[ \boxed {\cos \left (x \right ) y^{\prime }+\sin \left (x \right ) y=\cos \left (x \right )^{2}} \]
✓ Solution by Maple
Time used: 0.0 (sec). Leaf size: 10
dsolve(cos(x)*diff(y(x),x)+sin(x)*y(x)=cos(x)^2,y(x), singsol=all)
\[ y \left (x \right ) = \left (c_{1} +x \right ) \cos \left (x \right ) \]
