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 ⅆyⅆx, not dy and dx separated.

Examples

Example 1

ODE  dx yxx dyx = 0;

ODE:=dxyxxdyx=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:=yxxⅆⅆxyx=0

ODE1:=yxxⅆⅆxyx=0

(2.2)

dsolveODE1;

yx=_C1x

(2.3)
