I'm stuck on something that must be incredible simple to do. I calculate the second derivative of $f(x) = e^{\sin(x)}$ like so in Maple:
diff(diff(exp(sin(x)),x),x);
But now i want to calculate $D^2f(0)$, and can't seem to find a proper way to do this...
I tried:
fsolve(Deriv = 0, x);
with Deriv:=diff(diff(...))
but that gives me $1,57...$ but it has to be $1$.
