## show variable in outcome ...

i have a generator function but in out come i have phi(p_1,p_2,p_3, so on )=** result is clear but this p_1 and p_2 in not shown i want to be shown in my outcome

Maple

for 2D plot of 3D plot when parameter change there is an idea for making something like that, i need some help about this

## plot solution of PDE ...

```restart;

xi := beta[3]*(2*alpha*k*t + x)*sqrt(1/(36*alpha*beta[4] + 36*gamma*beta[4]));
params := {alpha = 2.5, k = 3, w = 2, beta[3] = 3, beta[4] = 1.7}

xi := beta[3] (2 alpha k t + x)

plot3d(rhs(sol1n), x = 0 .. 250, t = 0 .. 4);
```

how plot the the solution of PDE of this kind of function?
