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 ⅆyⅆx, not dy and dx separated.

Examples

Example 1

> 

ODE ≔ dx yx−x dyx = 0;

ODE:=dx⁢y⁡x−x⁢dy⁡x=0

(2.1)
> 

dsolve(ODE);

Error, (in dsolve) expecting an ODE or a set or list of ODEs. Received dx*y(x)-x*dy(x) = 0

Solution 1

> 

ODE1:=y⁡x−x⁢ⅆⅆx⁢y⁡x=0

ODE1:=y⁡x−x⁢ⅆⅆx⁢y⁡x=0

(2.2)
> 

dsolve⁡ODE1;

y⁡x=_C1⁢x

(2.3)
