hi,

What command can I use to solve the attached equation and draw its graph?

ode := -(q2-q4)*(q2-q3)*(q1-q4)*(q1-q3)*y(w)^2+(q1+q2-q3-q4)*(2*q1*q2-q1*q3-q1*q4-q2*q3-q2*q4+2*q3*q4)*(diff(y(w), w))*y(w)+(-2*q1^2-2*q1*q2+3*q1*q3+3*q1*q4-2*q2^2+3*q2*q3+3*q2*q4-6*q3*q4)*(diff(y(w), w))^2+(q1-q2+q3-q4)*(q1-q2-q3+q4)*(diff(y(w), w, w))*y(w)+(3*q1+3*q2-3*q3-3*q4)*(diff(y(w), w, w))*(diff(y(w), w))-3*(diff(y(w), w, w))^2+(-q1-q2+q3+q4)*(diff(y(w), w, w, w))*y(w)+2*(diff(y(w), w, w, w))*(diff(y(w), w)) = 0

-(q2-q4)*(q2-q3)*(q1-q4)*(q1-q3)*y(w)^2+(q1+q2-q3-q4)*(2*q1*q2-q1*q3-q1*q4-q2*q3-q2*q4+2*q3*q4)*(diff(y(w), w))*y(w)+(-2*q1^2-2*q1*q2+3*q1*q3+3*q1*q4-2*q2^2+3*q2*q3+3*q2*q4-6*q3*q4)*(diff(y(w), w))^2+(q1-q2+q3-q4)*(q1-q2-q3+q4)*(diff(diff(y(w), w), w))*y(w)+(3*q1+3*q2-3*q3-3*q4)*(diff(diff(y(w), w), w))*(diff(y(w), w))-3*(diff(diff(y(w), w), w))^2+(-q1-q2+q3+q4)*(diff(diff(diff(y(w), w), w), w))*y(w)+2*(diff(diff(diff(y(w), w), w), w))*(diff(y(w), w)) = 0

ans := dsolve(ode, y(w))

 Hi,

The problem of saving photos in eps format with a small size
When I draw a function diagram with Maple, when I save the photo in eps format, the size is high, but I want the size to be high and the volume to be low, what should I do? If anyone can and knows how to draw with MATLAB, write the code for me, I would be grateful
