Max of (sin(x))^(e^x)

[parisse]

If you are interested in approx. solutions, use fsolve.

Code:


f(x):=(sin(x))^(e^x);
fsolve(f(x)=1);
solve(f'(x)=0);

solve is for *exact* solving of polynomial-like equations, but this kind of equation f(x)=c is not solvable exactly for a generic second member c. solve will automatically switch to fsolve if there is an approx value inside.
