Error, (in dsolve) expecting an ODE or a set or list of ODEs. Received ... Description Maple does not recognize the differential notation dy(x) representing the differential of the function y(x). To enter a differential equation in Maple, you must form the actual derivative. Work with the derivative $\frac{ⅆy}{ⅆx}$, not dy and dx separated. Examples

Example 1

 >
 ${\mathrm{ODE}}{:=}{\mathrm{dx}}{}{y}{}\left({x}\right){-}{x}{}{\mathrm{dy}}{}\left({x}\right){=}{0}$ (2.1)
 > $\mathrm{dsolve}(\mathrm{ODE});$

Solution 1

 > $\mathrm{ODE1}:=y\left(x\right)-x\left(\frac{ⅆ}{ⅆx}y\left(x\right)\right)=0$
 ${\mathrm{ODE1}}{:=}{y}{}\left({x}\right){-}{x}{}\left(\frac{{ⅆ}}{{ⅆ}{x}}{}{y}{}\left({x}\right)\right){=}{0}$ (2.2)
 > $\mathrm{dsolve}\left(\mathrm{ODE1}\right);$
 ${y}{}\left({x}\right){=}{\mathrm{_C1}}{}{x}$ (2.3) See Also
