Pregunta: y' + y = sen x; y= 1/2 sen x - 1/2 cos x + 10e^-x

To verify whether the given function, $\mathrm{y}=\left(\frac{1}{2}\right)\sin \left(\mathrm{x}\right)-\left(\frac{1}{2}\right)\cos \left(\mathrm{x}\right)+10{\mathrm{e}}^{-\mathrm{x}}$ , is a solution to the differential equation y' + y = sin(x),...
