How to expand derivatives



(%i1) e : 1+exp(a*(x+b));
(%o1) %e^(a*(x+b))+1
(%i2) diff(e,x);
(%o2) a*%e^(a*(x+b))
(%i3) diff(e,a);
(%o3) (x+b)*%e^(a*(x+b))
(%i4) diff(e,x,2);
(%o4) a^2*%e^(a*(x+b))
(%i5) diff(e,x,1,a,1);
(%o5) a*(x+b)*%e^(a*(x+b))+%e^(a*(x+b))

To read the user documentation for 'diff,' at a command prompt,
type:  ? diff
