My textbook has an example on multiplication of power series.
" Multiply the geometric series [tex] x^n[/tex] by itself to get a power series for [tex]1/(1-x)^2 [/tex] for |x|<1 "
from this we get the [tex]c_{n}[/tex]=n+1
O.K. I get that the coefficients are 1 for all n but why +1.
Could someone please explain this to me if possible.
