    Taylor Approximation Proof for P(r) using Series Expansion

    [SOLVED] Taylor approximation Homework Statement I have an exact funktion given as: P(r)=1-e^{\frac{-2r}{a}}(1+\frac{2r}{a}+\frac{2r^2}{a^2}) I need to prove, by making a tayler series expansion, that: P(r)\approx \frac{3r^3}{4a^4} When r \prec \prec a The Attempt at a Solution...

    Relation between matrixes problem

    Hi, I have a problem with an argument here. I am given 4 Matrixes, A, C, D and F. see attachment.. I can then see that A^n = C*D^n*F = some matrix with a Fibonacci-serie in it. I can also see that C*F=F*C=I or C is the inverse of F My problem is to relate these two: How can the fact...
