CAS Maple gives this as type [`y=_G(x,y')`]

\[ \boxed {y^{\prime }-\sin \left (y\right )=-\cos \left (t \right )} \] With initial conditions \begin {align*} [y \left (\pi \right ) = 0] \end {align*}

Solution by Maple

dsolve([diff(y(t),t)=sin(y(t))-cos(t),y(Pi) = 0],y(t), singsol=all)
 

\[ \text {No solution found} \]
