GIven a polynmial in multiple variables, I'm looking for the Maxima
equivalent of the Maple function implicitdiff.
Say
f:=lamda^2-lambda*c-a*lambda+a*c-b^2=0
To implicitly differentiate lambda with respect to in Maple, I'd simply
enter
implicitdiff(f,lambda,c)
yielding
(a-lambda)/(-2lambda+c+a)
There is no straight equivalent in Maxima for the implicitdiff command
in Maple (not that I can find). Did find implicit_derivative, but I
can't seem to make out exactly what it does (since there are no examples
I could find that demonstrated it). Google didn't seem to help here much
either.
So, how does one do simple implicit differentiation in Maxima? Is there
a simple 'single command' to do the trick, or do I have to break up the
problem in pieces, somehow?
Pointers to the obvious appreciated.
Thanks very much in advance.
