Solve, 2xsinydx+x2cosydy=0. (1.9.3) Solution: This equation is separable, but we will use a different technique to solveit. By inspection, we notice that, 2xsinydx+x2cosydy=d(x2siny). Consequently, Equation (1.9.3) can be written asd(x2siny) =0, which implies thatx2sinyis constant, hence the general solution to Equation (1.9.3) is, c,
