Hey all :)

restart; 
W:=(x,t)->(8*R/Pi^2*sum((1/(2*n-1))^2)*sin((2*n-1)*pi/2)*sin((2*n-1)*pi*x/2*L)*(cos(c*(2*n-1)*pi*t/2*L)),n=1..infinity);
                
L:=0.25;
                              
T:=2500;
                             
rho:=0.01;
                              
R:=0.005;
                           
c:=sqrt(T/rho);

evalf(W); (this just comes up with W)
                          

I have tried...

Hi everyone.

I need to plot a graph of y against x for the solutions for values of t form 0 to 0.003 seconds using

c=50m/s

beta=10

A=0.01m

L=0.5m

The equation is y(x,t) = A*e^(-beta(x-L-ct)^2/(L^2))

I also need to show that the above equation can be a solution for (d^2y/dt^2) = c^2 * (d^2y/dx^2) on maple.

Cheers if anyone could help me with this.
