Hi,
I'm confused about the behavior of 'hipow' when the first argument contains
derivatives. For example consider
(%i1) depends(x,t);
(%o1)
[x(t)]
(%i2) hipow(diff(x,t)^2,x);
(%o2) 1
(%i3) hipow(diff(x,t)^2,diff(x,t));
(%o3) 2
(%i4) hipow(diff(x,t)^2,diff(x,t,2));
(%o4) 0
Output lines %o3 and %o4 make sense to me but I don't understand why
hipow(diff(x,t)^2,x) should evaluate to 1 instead of 0 (output line %o2). Is
there something I don't understand about hipow? I'm using Maxima 5.20.1.
Many thanks for your help.
