Dear Jay
just a quick follow-up:
I accidentally left the dx out of my first line in previous message. DE should be
2xsin(3y)dx+3x^2cos(3y)dy=0
Also my code for using ode2 is as follows...
(C21) de2:2*x*sin(3*y)+3*x^2*cos(3*y)*'diff(y,x)=0;
2 dy
(D21) 2 x SIN(3 y) + 3 x -- COS(3 y) = 0
dx
(C22) ode2(de2,y,x);
LOG(SIN(3 y))
(D22) - ------------- = LOG(x) + %C
2
which looks OK [can be shown to be same as x^2*sin(3y)=constant]
Also is there any way that the Maxima answer as given (D22) can be manipulated within Maxima to give the actual answer
x^2*sin(3*y)=a constant ??
kind regards
Stephen
