How to find all the terms of a polynomial that contain a specific variable in Matlab?
Let say that we have the polynomial f=a^2*b+b^2*c+c*d.
I would like to know if, in Matlab, I could find all the terms of f that
contain specific polynomials of variables a, b, c and d.
For example, if I have a polynomial of variable c, that is…

How to calculate sum of the given series
The nth term of the series is f(n).
f(n) = 1, when n=1
f(n)= ((n-1)*(8*(n–2)* 2+ 20)+4) , when n>1
P(n)=f(1)+f(2)+.....f(n)
1<=n<=10^9
for a given n we have to find P(n) modulo 10^9+7.
I solved the equation and finally…
