Sinh Gordon. Solve for \(u(x,t)\) \[ u_{xt} = \sinh u \]

Mathematica ✗

ClearAll["Global`*"]; 
pde =  D[u[x, t], x, t] == Sinh[u[x, t]]; 
sol =  AbsoluteTiming[TimeConstrained[DSolve[pde, u[x, t], {x, t}], 60*10]];
 

Failed

Maple ✗

restart; 
pde := diff(u(x,t),x,t)=sinh(u(x,t)); 
cpu_time := timelimit(60*10,CodeTools[Usage](assign('sol',pdsolve(pde,u(x,t))),output='realtime'));
