Dear everyone:
I am a beginner. Maybe the problem is so easy, but I really
have no idea about it after several failure attempt. Thanks for
everyone's help!
The problem is that :
Assume there is a rule about function P[n](x) such as :
P[n1](x) * P[n2](x) = sum( H(l) * P[l](x), l, 0,n2), where H() are
coefficients
eg. P[2](x) * P[4](x) = H(1)*P[1](x)
+H(2)*P[2](x)+H(3)*P[3](x)+H(4)*P[4](x)
Now ,there is a polynomial about P[n](x):
For example: P[2](x)*P[3](x)*P[4](x)+ P[2](x)^2 + ...
How can I apply the rule above in this polynomial in MAXIMA?
